Wanderers came from behind to beat fellow Premier League outfit in the FA Cup fourth round 2-1, but Brendan Rodgers felt his side deserved something from the game
The hosts fell behind to a Luke Moore goal, before Pratley scored an equaliser, and Chris Eagles netted a second half winner.
The former Swansea man has struggled to hold down a regular first team place since his summer move to the Reebok Stadium, but Coyle hailed the attitude of the midfielder.
“I think he’s been frustrated this season,” Coyle said.
“It’s great to see him hit the back of the net, but he could’ve had a hat-trick!
“It was great to see the energy he brought to the team and in scoring his goal I think he was very respectful of his former club with his reaction.”
Coyle praised the effort shown by his side as they came back from behind to beat Swansea and progress to the last 16 of the FA Cup.
“It was more than a win,” he said.
“I thought we were excellent today, we started really well and felt hard done by to lose the opening goal because we’d had various chances to be in front.
“But the reaction was great, in the second half we scored a great goal but should’ve added to it.
“When there’s a one goal margin anything can happen and I they had a chance late on but with all due respect the game should have been dead and buried long before that.
“There’s no doubt we were very deserving winners today.”
Coyle made three changes to the side that beat Liverpool compared to the ten changes made by opposing number Brendan Rodgers, and it was the home side’s cohesion that enabled them to gain control of the match.
Meanwhile, Swansea struggled, as a totally new side tried to gel and play in the way that the club has been doing this season, but they found it hard as lack of match time clearly began to tell.
However, Rodgers felt his side were unlucky not to be in the hat for the next round.
“I felt that we deserved something from the game,” Rodgers said.
“We weren’t at our best or nowhere near our best but I still felt we’d done enough to earn something out of the game at the very least.
“I made changes to ensure the team was fresh and put a lot of trust in the players but there were too many mistakes today, that was the problem for us.
“I have a big respect [for the FA Cup], I really wanted us to go through today and I picked a team to do that.”
The visitors took the lead through Moore against the run of play, but the move leading to the goal was typical Swansea and something the manager was delighted to see.
“The build-up was fantastic,” he continued.
“It’s what we’ve done a lot of this season, we worked our way through and it was a team goal.
“It was world class finish, he used his pace and his strength and a wonderful dink over the keeper.”
The game turned in the 56th minute when reserve goalkeeper Gerhard Tremmel spilled a Martin Petrov shot right into the path of Eagles and the winger calmly rolled the ball into the back of the net, but Rodgers refused to lay the blame at the door of his goalkeeper.
“There’s no blame attached to him,” he stressed.
“He doesn’t get a lot of game time, and we could’ve prevented their move for the second goal much sooner than we did.”
