Paul Hartley says it's no coincidence that Celtic's title surge has come at the same time as Neil Lennon's appointment to the coaching staff.
"He has been a big influence on the midfielders such as myself, Barry (Robson) and the rest of the squad. We all know what it's about and what it takes to win games because Neil led the club to championships as a captain.
"Neil has had a major influence. He has a chat with everyone in the team and it's nice to be able to talk to him because he knows what life is like at Celtic.
"He's added fire to the team and has been good to have in the dressing room. Players look up to him because of what he did in his time."
