Middlesbrough transfer rumours: In-demand striker assessing his options, Sunderland confident of contract boost plus Charlton reports

Here are some of the latest Boro-related rumours from around the web:

Cambridge striker assessing his options

Bolstering his side’s attacking options remains the priority for Warnock this summer.

The Teessders have been linked with Cambridge striker Paul Mullin, who scored 31 goals in League Two last season, while Blackburn and Preston have also been credited with interest.

Cambridge boss Mark Bonner has confirmed that Mullin will miss the start of pre-season as the forward continues to assess his options.

“He won’t be in training with us next week. He’s taking his time to meet people and see what other interest is out there,” Bonner said.

“I understand his situation of wanting to see what else is available to him. He hasn’t made that decision yet, so that is in his court.”

Sunderland confident of agreeing new deal

Another player who has been linked with Boro in recent weeks is Sunderland’s Luke O’Nien.

O'Nien will be out of contract this summer but has been offered a new deal at the Stadium of Light.

According to Football Insider, Sunderland are confident of agreeing a new contract with O’Nien amid strong interest from EFL rivals.

Championship clubs Luton, Millwall and Preston have also been credited with interest in the 26-year-old.

Sunderland have also offered new deals to Aiden McGeady, Denver Hume and Charlie Wyke.

Boro have been linked with Wyke yet it’s understood the striker isn’t on the club’s radar.

Charlton striker reports

Finally, Charlton have announced that striker Chuks Aneke will leave the club when his contract expires this summer.

Boro were one of several clubs to be linked with the 27-year-old frontman, along with Reading, Coventry, QPR and Bristol City.

Aneke scored 15 goals in 38 League One appearances last season and the Addicks were keen for him to stay at The Valley.

According to Football League World, the striker is on course to link up with his former manager Lee Bowyer at Birmingham.
