Brentford's Thomas Frank criticised his side's lack of composure as they surrendered a lead to fall to a 2-1 defeat at Sheffield Wednesday.

The Bees missed a chane to break into the play-off spots as Steven Fletcher's quick-fire double sent the Owls into the top six.

Bryan Mbeumo gave the West Londoners the lead in the 29th minute and should've atleast salvaged a draw late on but Said Benrahma curled effort went agonisingly wide as Wednesday held on.

"This is Championship football, so anything can happen," Frank said.

"We played a really good first half away from home in a lot of aspects.

"We didn't give any chances away, we played a good high line, we closed most of the crosses down and we created a lot of opportunities to go 1-0 up.

"Maybe we should have taken one of those chances to make it 2-0 because we know anything can happen in this league.

"The most disappointing thing was that we lacked that 'coolness' in terms of sometimes just keeping the ball or sometimes go for the kill.

"We lacked quality and decision-making and that extra good touch or pass to make it two-nil.

"Then after the equaliser from a strange penalty, we needed to stay in the game. We were absolutely sleeping from that quick throw-in.

"We knew that they wanted to put crosses in the box, we knew that Fletcher is a good striker so that goal is a very disappointing moment because I think 1-1 would still have been a good result here.

"In general, when you play so well in the first half you want at least a point, but football matches are 90 minutes and we need to do well enough over those 90 minutes but we didn't do that today."
