Nottingham Forest's Lewis O'Brien is determined to prove his detractors wrong.

The young midfielder has signed a loan deal with Middlesbrough for the rest of this season.

O'Brien wants to ensure he gets regular game time to showcase his true quality on the pitch, having struggled for game time at Forest.

“I wanted to challenge myself again and definitely wanted to come back and prove some people wrong really. I had to come back and show people what I could be," he said, per Nottinghamshire Live.

"My career trajectory was on the up at one point then it leveled off and things went wrong and I just feel like I still have places to go and to prove I can get to these places.

“There was outside factors that contributed to the things that have happened and it wasn't that I wasn't great at football or whatever people might think. I just want to get on the pitch and show people what I can do."
