Coyle made his 10th signing of the summer on Thursday when he snapped up Republic of Ireland international James McClean from Sunderland.
He still has £1million in reserve following the exits of Arouna Kone and Mauro Boselli, and it does not appear he has abandoned all hope of spending it either.
Certainly the huge number of reinforcements were required following the mass exodus of out-of-contract stars following Wigan's slide into the Championship.
"I inherited a squad of 11 first-team players," said Coyle, ahead of Sunday's Community Shield encounter with Manchester United at Wembley.
"Of those, Arouna Kone had a clause in his contract and went to Everton and Mauro Boselli went to a club in Mexico.
"The attitude of the nine who were left to get the football club back to where everybody craves it to be has been unbelievable but from those two transfer fees we have tried to wheel and deal and bring in good players.
"That there is still £1million that has not been spent shows how hard we have worked to bring in Grant Holt at £1.5million, James Perch for £500,000, Scott Carson, James McClean at a bargain fee.
"We think we have got quality and players with a real purpose."
After opening their league campaign with an impressive win at Barnsley, the FA Cup winners' strange season continues at Wembley, scene of their stunning triumph over Manchester City in May.
This time around, it is the other Manchester side that provide the opposition, the first excursion United have had to Wembley without Sir Alex Ferguson at the helm since 1985.
Coyle accepts it will be a strange experience knowing David Moyes is in charge of the men in red.
However, he is certain United have got the right man to replace Ferguson.
"David has succeeded Sir Alex on merit," said Coyle. "For years I have been saying he could manage any top club in world football.
"There is no doubting what he has done. He has been at the coal face with Preston and earned the right to go from there to Everton, where he also did a magnificent job.
"He was a natural successor to Sir Alex and it is great to see a home-grown manager evolving to that level.
"I have no doubts he will have huge success at Manchester United."
