Boss Gareth Southgate insists everyone at Middlesbrough owes Bryan Robson a debt of gratitude - but concedes his departure from Sheffield United has increased the chances of an FA Cup upset on Sunday.

And the former England defender admits he is disappointed at the way Robson´s latest management role at Bramall Lane ended, especially as it is likely to give the home fans a boost when Boro travel to South Yorkshire.

"It probably doesn´t make our job any easier because, as we know, the supporters at Sheffield United were a bit anti-Bryan and with the new man (Kevin Blackwell) going in, they will presumably have a new lease of life, however temporary," he said.
