Fulham manager Mark Hughes said he was left “frustrated” by the officials as his side were knocked out of the FA Cup following a 1-0 loss to Bolton.

Ivan Klasnic’s goal in the first half proved enough to put Bolton through to last-eight tie at Birmingham.

“Bolton went ahead, then they got people behind the ball,” said Hughes.

“We were frustrated with the officials. I don’t think they got enough decisions right during the match but that was the same for both teams.”

One incident in the first-half saw both Hughes, his staff and the home support vent their fury at referee Stuart Attwell for not taking action against Bolton’s defenders, who appeared to pull back forward Moussa Dembele on the edge of the area.

Hughes added: “We questioned a number of those situations and on this occasion the ref said he was playing the advantage. It was on the edge of the area so we would rather have had a free-kick.”

We’ll field a attacking line-up at Birmingham because we want to win,

The Welshman, who won the FA Cup on four occasions as a player, said his side lacked invention in the attacking third.

“Bolton have good competitors everywhere – they were able to keep us out,” he continued.

“We dominated after the break and it was one-way traffic. We needed poise and guile in the last third.”

Hughes also welcomed the return of striker Bobby Zamora, who returned to first team action in the second half having been out since September with a broken leg.
