“I am very excited to work under (manager) Russell Martin, as he was a huge influence in me making my decision to join the Dons.
“I’m looking forward to the style of play as I feel it plays to my strengths and will give me the opportunity to score goals.
“I am a goalscorer, but most importantly I am a team player and I always try to do my best for the team to win.
