Celtic “have only themselves to blame” after suffering a Champions League exit shock in Glasgow at the hands of Ferencvaros, manager Neil Lennon said.
The Scottish champions trailed behind their Hungarian counterparts, but equalized Ryan Christie before conceding late to enter the Europa League.
The defeat follows home outings in the last session at the hands of Cluj and FC Copenhagen in continental competition.
“It looks like we made the same mistakes as last year,” said Lennon.
“The first goal, maybe we can legislate a little bit, but the second goal is really bad decision making.
“I don’t know if it’s an attitude or a mentality, but it cost us again. I’ll have to carry the can and take responsibility for it. ”
Celtic were beaten 4-3 at home by Cluj of Romania in the Champions League third qualifying round last season, then lost 3-1 to the Dane Copenhagen in the Europa League last 32 in Glasgow.
Both were ties Lennon’s side needed to win, just as they were against Ferencvaros, who instead referred them to the Europa League third qualifying round draw on Tuesday.
“The game was actually a lot easier than I thought it would be, but we didn’t take our chances and we had a lot,” Lennon told BBC Scotland.
“I’m not saying Ferencvaros is a bad team – it isn’t – but we had so much control we should have won. It doesn’t make us weak, it doesn’t make me weak, but people are going to throw criticism. ”
Asked what message he would give to his players, Lennon added: “Have a good mindset, have a good attitude. If some of you don’t want to be here, go. ”
When asked if his impression was that some players did not want to be at the club, he replied: “In some cases”.
