EXCLUSIVE: Middlesbrough, Derby chasing Aberdeen hitman

Aberdeen striker Sam Cosgrove is being chased by a host of Championship clubs, we can reveal.
The former Carlisle front-man has impressed hugely at Pittodrie since joining in 2018.
Cosgrove signed a new deal back in January, but it is understood that the striker would be available for less than £2million.
We understand that Derby, Brentford, Charlton and Middlesbrough have all checked on the forward in recent weeks.
