"Jullien needs some game time so he will start," said Lennon. "There's a few players we want to get up to match sharpness.

"He's been patient, he's worked very hard, he's had a couple of bounce games and he's ready to play now."

Lennon revealed Callum McGregor and James Forrest have not travelled in order to give them a rest ahead of Saturday's Premiership opener against St Johnstone.

Despite Celtic being all but certain of a place in the third qualifying round, and a tie with either Israeli side Maccabi Tel-Aviv or Cluj of Romania, Lennon has demanded another professional performance.

"Obviously we are in a very strong position but it's a game we want to win," he added.

"We'll change a few of the players but we're here to win the tie and keep the momentum going with the league campaign starting on Saturday.

"Complacency is your enemy in a situation like this. Most people will see Celtic's qualification as a foregone conclusion but we have to be as professional as we can.

"It's important to come here, compete and try to win the game. These are difficult ties in the Champions League and we must prepare the team as best as we can."

Kalju may face a thankless task but the match, moved to the 14,400-capacity A. Le Coq Arena, is still a huge occasion for the hosts.

Coach Roman Kozhukhovskyi said: "We are very much looking forward to the game and will go into it with maximum effort.

"It has been a very busy week with a lot of analysing the mistakes we made in Glasgow and trying to eliminate them in Tallinn. It's a big game and no one needs extra motivation."

Captain Maximiliano Ugge smiled as he added: "This is football, anything can happen.

"We know that scoring five goals is certainly not easy, but we'll do our best."
