Middlesbrough continue to keep tabs on Denver Hume and Charlie Wyke as they weigh up whether to move for the out-of-contract Sunderland duo, a source has exclusively revealed to Football League World. 

Sunderland were beaten in the League One play-off semi-finals by Lincoln City last month, with Lee Johnson now preparing to lead the Black Cats into a fourth consecutive season in the third-tier.

The club's retained list confirmed that Hume had been offered a new contract, whilst ongoing discussions were taking place with Wyke on the back of a 26-goal season.

As things stand, though, both are out of contract at the end of this month, with a source revealing to Football League World that Neil Warnock is a fan of defender, Hume, who has yet to make a decision on the contract Sunderland have offered.

Although not a like-for-like replacement for Dael Fry, the 22-year-old is a potential option to come in and bolster Boro's ranks if they lose one of the EFL's leading centre-backs this summer. It is our understanding that Brentford have made Fry a transfer target this summer, whilst other top-flight clubs have scouted the 23-year-old.

It's also been explained to Football League World that Boro have an eye on Wyke as they look to revamp their attack after the departures of Ashley Fletcher and Britt Assombalonga.
