Celtic lost to Romanian side Cluj 5-4 on aggregate.
Neil Lennon's tactics have been called into question after Celtic were dumped out of the Champions League by Romanian outfit Cluj.
The Scottish Champions were beaten 5-4 on aggregate - losing 4-3 at home last night.
Prolific Celtic midfielder Murdo MacLeod, who played 281 times for the Glasgow club, scoring 55 goals, questioned the fact Lennon played three at the back and made several attacking players put in a shift in defence.
MacLeod, speaking to Love Sport Breakfast, said: "Celtic didn’t start the game well. Usually with a European tie at home there’s a good atmosphere but it was very flat for the first 20mins.
"Cluj went in front and then you think we’re chasing it now.
"Towards the end of the game, after 3-3, they ended up losing a fourth goal. It was a poor performance overall last night.
"The talking point last night with Celtic playing three at the back, and that wasn’t the usual set-up. Forest filling in at right and left back, that didn’t really work last night."
Celtic missed out on more than £20m by being dumped out of the Champions League, but MacLeod thinks the sale of Kieran Tierney for £25m will satisfy the board.
MacLeod said: "I don’t think so. Look what’s happened with Kieran Tierney going to Arsenal, that’s £25m going into the bank. That’s maybe for the board’s side. But from the fan’s side that’s a massive part of the season to get in the Champions League."
Asked whether he thinks Lennon is still the right man for the job at Celtic, he added: "I think he has been. He’s had a fantastic start to the season and that’s why so many Celtic fans will be shocked today.
"The European campaign was going nicely and going back to Celtic Park with a 1-1 draw away from home.
"And then we lost the match 4-3 it’s very sore to take. I don’t think Neil will be under any pressure. He’ll just get on with it and see what’s going to happen in the Europa League."
