Hull City fullback Andrew Robertson feels there's more to come from him.
The Scot has been a revelation since his arrival from Dundee United.
"I have not put in a complete performance yet,' he told the Daily Mail. "Hopefully I can do that soon but so far I'm pleased.
"It's a great league to play in and I've enjoyed every game, but I know I can show a lot more. Steve Bruce has been brilliant with me, helped me through a lot already and tweaked things in my game.
"I know I'm still young, so that's what has to happen.
"I'd say the tempo would be the biggest difference and it's much more physical. So I need to work on my fitness, be a lot quicker. I'm learning a lot with better players around me.
"I'm trying in the gym to build up and get stronger but I don't want to do too much too soon. It's a gradual improvement we're looking for and I'll just keep on doing my programme and, hopefully, see the results."
