Fulham boss Chris Coleman was forced to field a weakened team for the second-round clash, partly as a result of the club’s mounting injury problems.
But the former Wales international had stated the side should be strong enough to knock out Wycombe and he blasted tonight’s lacklustre first-half display.
‘It was a poor display from us in the first 45 minutes,’ he said.
‘At half time some of the lads looked like they were on the night shift when they really wanted to be on the afternoon shift on Saturday.
‘We need to get that first half out of our system. It was different in the second half and we scored early doors.
‘After that they got a lot of men behind the ball and made it difficult for us.’
Fulham’s injury woes increased when Bocanegra limped off in the second half with Coleman revealing the USA defender had been earmarked for the midfield in Saturday’s Barclays Premiership clash with Chelsea.
‘Unfortunately Carlos Bocanegra came off with a sore groin. I didn’t want to play him tonight because of a lack of bodies for Saturday but we had no option,’ he said.
‘Now we don’t know if he’s going to be available for Saturday. He played in midfield for us against Tottenham and did a wonderful job.
‘He was tired tonight and we were debating whether or not to play him. But we had to put some experience on the pitch. We hope and pray it’s not too serious.
‘If he’s not fit for Saturday then we don’t have many people to choose for in midfield.’
