Lee Trundle has certainly earned the tag of super sub after he came off the bench to fire the Swans to victory against Plymouth.
Paulo Sousa decided at the break to change things around and duly threw Trundle and Gorka Pintado into the fray, and altered the formation to 4-4-2.
And it was the two subs that combined to put the hosts ahead shortly after the interval, Pintado picking out Trundle at the near post with a cross from the right-hand side.
Dorus de Vries made a fine acrobatic save to deny ex-Swan Rory Fallon but the hosts held on to clinch all three points against a side that ended the game with 10 men following Shane Lowry's injury-time dismissal.
Besian Idrizaj made his full Swansea City debut against Plymouth. The 22-year-old Austrian front-man replaced Gorka Pintado in attack to make his fourth appearance for the club following his summer arrival.
His three appearances to date, the last back in September, all came as a substitute while his last Football League start came for Crystal Palace back in November 2007.
Alan Tate returned from suspension to skipper the side, replacing Albert Serran in defence, while Joe Allen, Leon Britton, Nathan Dyer and David Cotterill also came into the side.

Paulo Sousa opted for a change in attack for this game at a saturated Liberty Stadium with Besian Idrizaj lining-up as the lone striker.
And the move to replace Gorka 'El Toro' Pintado could have been justified within the first 40 seconds of this match as the Austrian played a part in the game's opening attempt.
Former Liverpool youngster Idrizaj sent the pacy Nathan Dyer on his way into the box following a one-two, as he charged down on goal the ball was cleared into the path of Joe Allen, the midfielder taking a touch before seeing his shot deflect wide for a corner.
The visitors applied some pressure in the proceeding moments but it was Allen again who had the next attempt with eight minutes played, that was cleared and Angel Rangel, making his 100th league appearance for the club, shot into the side netting from the angle with the follow-up.
Like Peterborough at the weekend Plymouth are a team in need of points, but they certainly didn't look like a team struggling at the foot of the table during the first quarter of an hour.
Paul Sturrock's side were able to hold the ball and a goalbound Jamie Mackie strike had to be blocked on the six-yard box by Ashley Williams.
But back came the Swans with full debutant David Cotterill putting pressure on the visiting defence on two occasions in quick succession - the first effort blocked by a defender while the second, curling goalbound, struck the chest of Idrizaj.
The visitors were forced to make a change midway through the first-half as Yoann Folly went off with a knock he picked up minutes earlier and his replacement, Chris Clarke, was amongst the action straight away as his dangerous ball into the box was narrowly missed by the head of Mackie.
Neither side were causing each other problems but the Swans did enjoy a spell of dominace around the half-hour mark.
Paulo's side were awarded a free-kick in dangerous territory following David Gray's challenge on Nathan Dyer, which resulted in a booking, but Cotterill drilled his effort wide from the resulting set-piece.
Barely a minute later and Besian Idrizaj was inches from connecting with Dyer's right-sided cross, only for it to be cleared from underneath the crossbar for a corner, but from Cotterill's flag-kick the former Austrian Under-21 international connected but was way off target.
This was the hosts' best spell of the half and with eight minutes to go before the break they created another opening, this time with Dyer dummying Gray on the left and crossing into Joe Allen's path, he lost out but Darren Pratley picked up the pieces and saw his fierce strike deflect wide for another corner.
Paulo's side finishes strongest, too, and on the stroke of half-time were handed their best chance of the half when Pratley was grounded just outside the area - Cotterill and Bessone stood over the ball, the latter struck it and all it needed was a slight deflection to take is just over the top of Romain Larrieu's goal.
The eventual corner found its way to Joe Allen but the youngster was unable to hit the target.
Half-Time: Swans 0 Plymouth 0
Paulo decided that a shake-up was needed at the start of the second period, the manager switched to a 4-4-2 formation and with that came two changes on the field.
Besian Idrizaj was taken off and replaced by fellow striker while Joe Allen also made way for the weekend's two-goal hero, Lee Trundle.
And the change worked wonders, the two substitutes combining to give the Swans a 52nd minute lead - Nathan Dyer released Pintado down the right-hand side of the area, he crossed low towards the near post where Trundle was ideally placed to tuck the ball between the 'keeper and the post.
The pressure on the Argyle defence was continuous with the newly introduced duo, with the aid of Cotterill, Dyer and Pratley, were causing havoc.
But as the Swans went searching for a second it was a former Liberty striker that almost snatched a leveller just after the hour.
The New Zealand star shrugged off his marker to find space inside the area where he was able to meet Chris Clarke's deep cross, sending his header goalbound only to be denied by an excellent acrobatic stop by Dorus de Vries who pushed the ball out for a corner.
Attention swung firmly back on the visiting penalty area as Lee Trundle won his side a corner, Cotterill's cross was cleared into the path of Angel Rangel who took a wild swing at the ball and only missed the goal by yards.
The frustration was certainly getting to the Argyle players and after picking up their fifth booking of the night inside the final 10 minutes they gifted their hosts with a chance to go for a second.
Skipper and former Wales international Carl Fletcher cleared the ball straight into the path of Nathan Dyer midway inside the Pilgrims' half, he skipped past two players and beat Larrieu with his strike from the edge of the area but failed to hit the target.
David Cotterill had enjoyed his full Swansea City debut as he caused no end of problems for the Argyle wingers, but Paulo decided that his night would come to an end four minutes from the end as he was replaced by Andrea Orlandi.
The second-half was largely dominated by the Swans but to make matters worse for Plymouth they were forced to play the remaining minutes of the four added on for injury-time with 10 men - Shane Lowry received his marching orders, picking up a second yellow for striking Gorka Pintado.
Trundle had one final half chance in the closing seconds but the referee's final whistle was blown moments later to signal the end of this game.
