Middlesbrough manager Aitor Karanka has criticised his players for mistakes made in their narrow defeat at Watford on Saturday.

Troy Deeney's penalty was enough for the Hornets to seal victory after some early pressure from Boro, but the visitors were unable to get back into a game in which both sides were reduced to 10 men early in the second half.

"I am angry and frustrated. We keep making mistakes and maybe some players think they are better than they are," he told reporters.

The Teesiders have now gone five games without a win or a goal and drop into the bottom half of the Championship after their defeat.
