Bolton Wanderers manager has criticised his players for switching off as they sacrificed a two-goal lead by drawing 2-2 at home to basement-boys Portsmouth on Saturday afternoon.
The Trotters motored in front thanks to goals from strikers Ivan Klasnic and Kevin Davies, but a fighting Pompey comeback spoiled the party at Reebok Stadium.
On-loan Lens forward Aruna Dindane bagged a second-half brace and the turnaround did little to make Coyle happy.
Speaking to reporters, he said: "My initial instincts were that some of the players probably felt they had the game won.
"And this level that can't happen because it will come back to haunt you and that's what happened today.
"I think at 2-1 the players probably got a little bit edgy, knowing that if we'd won the game then you're obviously safe in the Premier League.
"They probably just got a little bit too nervous if truth be told.
"That's something that we have to develop and add that mentality - that they have to see that through and be oblivious to everything going on around and be focused, have that tunnel vision to go and win the game."
