Manchester United boss Louis van Gaal is adamant he is taking nothing for granted when his side face Cambridge United in the FA Cup on Friday night.

The Premier League giants will take on the League Two outfit at Abbey Stadium, with both Dutch international Robin van Persie and England defender Luke Shaw available for the game, having missed the 2-0 win over Queens Park Rangers in the Premier League last weekend.

Former Barcelona keeper Victor Valdes is also in line to make his first start for United, having signed an 18-month deal at Old Trafford.

Spanish keeper David de Gea has been the first choice between the sticks but the FA Cup might well provide Valdes with the opportunity to get some game time under his belt.

Van Gaal is taking the encounter with Cambridge seriously and does not want his side to be the victim of a giant-killing act in the fourth round of the cup.

He told reporters: “We have to be alert to play against them. I have to analyse training, the game-plan and who is the most suitable choice.

“The FA Cup is very important for fans and players. Attendances are much higher here than in Germany or Spain.”

United are 1.18 to avoid a slip against Cambridge.
