Former Cambridge forward Steve Claridge on 5 live Sport"This is what it's all about, being at Old Trafford as a Football League fan. This will live long in the memory for these Cambridge fans, particularly that incredible achievement of the first tie, drawing with Manchester United."

The 6,000 away fans are still bouncing and making plenty of noise. A terrific effort, having done battle with the M6 on the way too. They've not been embarrassed and will have that tremendous showing in the first leg to look back on for many a year.
And £1m+ in the bank too.

BBC Sport's Simon Stone at Old Trafford: "That's two in four games now for James Wilson.
"Interesting he has been given a chance off the bench despite the presence there of Radamel Falcao.
"The 19-year-old does not look out of place in this company that's for sure. And strikers who drop deep, as Wilson likes to do, give defences a headache."

Ashley Young is back with an overhit cross from the left as we enter the final 10 minutes. It's a very subdued atmosphere.

Former Cambridge forward Steve Claridge on 5 live Sport"They have done as well as you could have expected, for Cambridge. They had a glorious chance early on. I expected Manchester United to do more when they had the ball, but ultimately I suppose this is a satisfactory result for both sides, really."

Former Cambridge forward Steve Claridge on 5 live Sport"That's nice for James Wilson, and a good finish after a nice little turn. Low and hard into the bottom corner, not giving the keeper any chance. That will do his confidence no harm whatsoever."

That tie will be a big deal in Preston, and after a run of no wins in seven it could kickstart North End's faltering promotion push too. Simon Grayson has an FA Cup win over Manchester United under his belt.
Wayne Rooney is close to a fourth but mishits his shot.

A nice moment for Preston striker Joe Garner, who ends an injury absence of more than two months by coming on for the last three minutes. He starts with an ambitious shot from 40 yards. You can do that when you're 3-1 up.

BBC Radio 5 live sports extra"It was a great penalty, to be fair. It looked like a soft award to me though. The referee immediately pointed to the spot, but the Fulham fans are not happy with that whatsoever."
