Rodgers looking to add
Manager Brendan Rodgers wants even more competition for places at Celtic.
The Northern Irishman is therefore very keen to make further top-class signings over the summer and admits things are already well in motion to do exactly that.
"You can never become complacent," Rodgers warned BBC Scotland. "The players have improved, they're going to improve even more and gain more confidence next season.
"And if we can add one or two to that with genuine quality, then it just makes the group really competitive on a daily basis, and that will improve them in the games," he added. "We're very much wheels in motion, looking to improve and bring more quality to the squad as opposed to numbers. That's well underway."
