The 26-year-old also likened his relationship with former boss Aidy Boothroyd to "buying a petrol car and putting diesel in it".

Ellington fell out of favour with the Hornets boss after he admitted he wanted to team back up with former manager Paul Jewell at Derby, for whom he signed in June.

He told the Watford Observer: "The way the season panned out meant it was my worst season in football. The best thing was to move on and start afresh.

"I told him three for four times I was not getting any games and I need to move on and find someone who is going to play me, but I felt it was like buying a petrol car and putting diesel in it.

"I'm pleased to have it sorted and be back with my old manager. He knows me best and knows how to get best out of me."
