Coventry City manager Tony Mowbray has said that he is interested in offering Ruben Lameiras a deal.
Mowbray told the club website: "When we brought him on, I think he made a big difference.
"He showed some good touches and always wanted to get on the ball. He has a good first touch and turn, and was definitely a threat for us.
"He's goal-bound shot was well blocked and I've been generally impressed with what I saw from him.
"I like his attitude in training and I think over the coming days, we'll look to tie him down on a deal."
