Chelsea have agreed to pay Millwall £175,000 for their 6ft 5in academy keeper Sam Walker.

The Lions last week turned down a double bid from Portsmouth for Walker, 15, and defender Tom Kilbey, 17.

Millwall have banned Premier League scouts from watching academy games without club clearance, says The Sun.

Boss Willie Donachie said: "They are trying to poach our players and we don't want them sniffing around."
