Middlesbrough boss Aitor Karanka says more transfers may follow Patrick Bamford's return to the club, as they seek to improve on 16th place in the Premier League.

"The club is working well behind the scenes and knows the players I like and would want to bring in. As a coach I always have a lot of options in my head for how we can play each game.

"If we win this game we can open a gap at the bottom. But it is a tough league and we have to battle until the last moment."
