Three goals in six first-half minutes set Cambridge on the way to a dominant 4-0 win over Fleetwood as they booked a place in the third round of the FA Cup.

The U’s, with Barry Corr in caretaker charge following the sacking of manager Mark Bonner on Wednesday, never looked back after Danny Andrew opened the scoring in the seventh minute.

Andrew curled in a free kick from 22 yards, awarded after Elias Kachunga had been fouled by Bosun Lawal.

Four minutes later Kachunga was on the scoresheet himself, netting from close range after Sullay Kaikai’s shot had hit the post.

In the 13th minute, Kaikai set up Fejiri Okenabirhie who ran clear and finished confidently.

Brendan Wiredu put Fleetwood’s best chance wide from close range before the U’s missed a penalty in the 29th minute. Gassan Ahadme’s tame effort from the spot was easily saved by Stephen McMullan after a foul on the lively Kaikai by Lawal.

Ahadme made amends in the second half, converting Paul Digby’s 83rd-minute cross to complete the scoring
