Wycombe booked their place in the quarter-finals of the Carling Cup after beating League Two rivals Notts County.

The Chairboys deservedly progressed thanks to Jermaine Easter's second-half strike after Saul Deeney had failed to gather Scott Goldbourne's cross.
Wycombe had the better chances and Tommey Mooney forced a fine save from Deeney while Easter's shot was blocked.
For County, Junior Mendes blazed over and Mike Edwards saw a close-range header tipped away by Ricardo Batista.
County's highest crowd of the season - 7,395 - turned up at Meadow Lane to see sixth-placed County take on Wycombe, three places higher in League Two.
It was the visitors who made the brighter start as they sought revenge for a 1-0 defeat against the Magpies in the league in August.
Twice they went close early on, first Mooney forcing a brilliant save from Deeney, before Edwards superbly blocked Easter's goalbound effort.

Wycombe's front three - Easter and Mooney were joined by Kevin Betsy - were causing County all sorts of problems and Mooney and Easter went close again as they piled forward.
Mendes replied for the hosts, but he twice shot wide from the edge of the box and missed a golden chance when he blazed over from close range.
After an enterprising first half, Wycombe took a deserved lead just after the break when Easter struck his 12th goal of the season, but it was largely thanks to a mistake from Deeney.
Goldbourne sent in a cross from the left and Deeney fumbled the ball into Easter's path, the striker making no mistake from 12 yards.
County made three changes as they went all-out for an equaliser and veteran hitman Jason Lee saw Batista claw away a header 10 minutes from the end.
Batista made another fabulous save right at the death, pushing a Daniel Martin shot around the post as County failed to take the game into extra time.
Notts County manager Steve Thompson:
"Wycombe have given us our hardest game in this competition so far, no disrespect to Crystal Palace, Middlesbrough and Southampton.
"I think they are the best team in our league. I knew it would be tight and they'd come at us from the start.
"They certainly defended very well but we had chances to get some goals."
Wycombe boss Paul Lambert:
"I was particularly pleased for Tommy Mooney and Jermaine Easter. They worked their socks off all night but so did all of our players.
"Our goalkeeper and defenders were excellent when County threw everything at us in the closing stages and I couldn't have asked for more.
"I'm absolutely delighted and it's reward for an excellent performance."
