"Since I came back, I've tried to train as well as I can and impress the manager, which I feel I have with the appearances I've made.
"We've had a lot of good results in recent weeks and, since coming back, I've noticed a big change and positive ones. We want to carry on and finish the season as strongly as possible. Personally, I want to get as many minutes as possible and try to make an impact."
