I’m really pleased to be here because it’s a club clearly going in the right direction and with real ambition.
I’m relishing the chance to play my part in a team that is challenging in the top half of the division. I have heard nothing but good things about the club and its close-knit group of players, so I’m really looking forward to it.
I’ll be looking to get my head down, work hard, and earn a place in the team to show everyone around the club what I can do.
