Watford boss Aidy Boothroyd admits he's unsure over the status of on-loan Middlesbrough winger Adam Johnson.

"I have had a good chat with (Middlesbrough manager) Gareth (Southgate), and it is difficult to nail down whether we can keep him for a longer term," he said.

"It is dependent on what happens with injuries, but we want to keep him. I feel he needs a full season at Championship level."
