Brentford and Nottingham Forest are haggling over a fee for Brennan Johnson.

The Daily Mail says Brentford have indicated they are willing to pay £15m for exciting attacker Johnson.

But Forest want at least £18m for Johnson, 20, a product of their academy, a sum that would top the £17.5m deal Brentford agreed to sign defender Kristoffer Ajer from Celtic last summer.

The Championship side also want a 15 per cent sell-on included in any deal for Johnson.

Johnson is in no rush to leave Forest, the side his Dad and former striker David once played for while the club also want him to stay.
