Leicester’s misery after their 3-0 loss to Manchester United on Sunday was compounded by the news right-back Ricardo Pereira has been ruled out for “about four months” with a hamstring problem.
Pereira missed the trip to Old Trafford after being withdrawn late on in the 1-1 draw at Ipswich the week before.
“It’s bad news – Ricky will be out for about four months with a serious hamstring injury,” Cooper said post-match.
“It’s a real blow for everybody, and especially him. We’ll all be with him now in his recovery.”
The Foxes had chances in the loss to the Red Devils – registering five shots on target to their opponents three – but failed to find a way past Andre Onana in the United goal.
“There’s nothing good about a 3-0 defeat, and we’ve not done enough to stop their goals,” Cooper added.
“We got into more than enough positions to threaten United’s box, but as a team we didn’t show enough.
“In large parts the game seemed even, but in certain moments we’ve not done enough at both ends of the pitch. We’re not going to hide away from the chances and goals we’re conceding, and we’ll keep showing intent to improve that.
“We know we have creativity and threat in the team, but didn’t maximise that.
“Whether it was a mixture of United being really ruthless stopping us, whether we could’ve made better decisions or shown more quality – it could be all of those things.”
