Brentford boss Leroy Rosenior says his young team must stop conceding goals by switching off as they bid to end a run of seven winless games when they host Bristol City on Saturday.

Following Saturday's 2-1 home defeat by Yeovil, Rosenior said: "I know we missed chances, but one thing we can't do is switch off and we did that twice.

"It's naive. It is about marking. We didn't do that and got punished for it.

"You do not get points if you do stupid things."

Rosenior is hoping Jo Kuffour, who has been playing with a back injury, Oli Skulason and Andy Frampton will be fit to face Bristol.

He said: "I cant recall having so many players out.

"Kevin O'Connor was only 80 per cent fit and Kuffour had to go off.

"Fortunately, we didn't play in mid-week, so we can get players fit for the big test on Saturday."

Brentford clawed their way back into the match against Yeovil thanks to Kuffour's equaliser, but were caught napping with just two minutes to play.

Following a quick throw-in on Brentford's left, Marcus Stewart worked the ball to Chris Cohen, who fired past Stuart Nelson to condemn the Bees to their second home defeat of the season.

The Bees had welcomed back skipper O'Connor and Thomas Pinault, who both missed the trip to Millwall.

Adam Griffiths, playing with a broken nose, was defending well, but his centre-half partner Matt Heywood made the kind of error that Brentford can ill afford as their young side looks to consolidate in League One.

With almost an hour on the clock, a Cohen corner from the right was met by Terry Skiverton, who got in front of Heywood to head past Nelson.

The Bees introduced fresh legs in Gavin Tomlin, Alex Rhodes and Ryan Peters and, with 10 minutes left, they pulled level.Tomlin's shot was blocked, but the ball fell to Kuffour, who bundled it home.

Calum Willock missed a chance and the, right at the death, Cohen to complete a smash-and-grab raid.
