Luke McCowan knows he must raise his game if he's to become more than a bit-part player at Celtic. The midfielder, who joined from Dundee two years ago, made just 16 starts across 42 appearances in all competitions this season, contributing four goals and three assists, as Martin O'Neill's side won the double. McCowan last month signed a new contract to stay at Celtic until summer 2028, but is not content to rest on his laurels.
