Craig Gardner has hailed the impact of Darren Fletcher at West Bromwich Albion.
Fletcher only arrived last month from Manchester United.
Gardner said: "He is brilliant, just the way he is around the dressing room and the training ground and on the pitch, his advice.
"He is a true leader. He is someone you can talk to. He was at United for many years which says everything. He's just a top class person.
"The boss gave him the captaincy and that is what gaffers are paid for - to make big decisions."
