Middlesbrough are interested in signing Sunderland forward Ross Stewart in January, according to reports.

The 26-year-old has been sidelined with injury since August, but he started the season in phenomenal form by scoring five goals in his first seven league matches.

With Stewart expected to return to action after the World Cup, Boro boss Michael Carrick is keen to make him a top transfer target when the transfer window reopens in the New Year.

The Scotland international’s contract expires at the end of the season, although Sunderland do have an option to extend his stay at the Stadium of Light for another twelve months.

Stewart will, therefore, not be sold on the cheap but it has been reported that chairman Steve Gibson will back Carrick in the market if the right player becomes available. Considering the striker’s outstanding goal record in recent seasons, he would certainly qualify.

Rangers were after Stewart back in the summer but they have since cooled their interest so Middlesbrough won’t have to worry about competing with the Scottish Premiership club.
