Celtic boss Neil Lennon has hinted at a formation switch for the Europa League last-32 clashes with Copenhagen.

The manager has been delighted with his 3-5-2 tactic that has had Leigh Griffiths partnering Odsonne Edouard up top and James Forrest reverting to a wing-back down the right and Greg Taylor on the left.

Still getting used to that tactic, however, Lennon's troops have a tried-and-tested 4-4-2 and 4-3-3 formations they've used in their Europa League group earlier this season where they romped to top spot.

And Lennon suggested he'd happily change back again to a back-four should the opposition shape dictate. "We looked at the formation to the wingers and changed it a little bit," Lennon said of switching tact during last night's 5-0 win over Hearts.

"We're flexible with the new formation and we can adapt back to the 4-3-3. With a back four in Europe, we've been very good so we'll always look at it."
