NEIL Lennon tonight admitted that Celtic still have work to do to get their supporters back onside - despite recording back-to-back wins for the first time in over two months.

A group of disgruntled fans staged a protest outside Parkhead before the Premiership match against Kilmarnock this afternoon.

Lennon, whose side has crashed out of both the Betfred Cup and the Europa League and fallen 13 points behind Rangers in the league in recent weeks, has faced calls to be sacked.

But the Northern Irishman and his team, who had beaten Lille 3-2 on Thursday night, were cheered into the stadium by the crowd that had gathered and went on to triumph 2-0.

The Celtic manager admitted that he and his players had been buoyed by that backing – but confessed they must go on a prolonged winning run and resurrect their 10-In-A-Row bid to end the off-field unrest.

“It was wonderful and I think the players really appreciated that,” said Lennon. “We just want unity.

“We understand the fans’ frustrations. We’re out of the League Cup and we’re out of Europe, so now we concentrate on the league.

“So it’s important that the fans get behind us, but we have to replicate that with performances and results.

“So it has been a good day, but that’s all it has been so far. It won’t placate all of the fans, because of that position we are in, so we have to work at it and make it better.”

Lennon’s team, who have two games in hand, won yesterday thanks to second-half Mohamed Elyounoussi and Shane Duffy goals.

The Celtic manager said: “He (Duffy) has had a difficult time off the field. This was sort of a fresh start for him and it probably didn’t pan out for him the way he had envisaged.

“But I’ve been there myself, so I know what it is like. I’ve been up at his house sometimes check he is okay, because he is up here on his own. He is settling in now and I think he will be great for us going forward.”

Mikey Johnston made his comeback for Celtic after 11 months out with calf injuries when he came on as a late substitute.

Lennon said: “We’ve missed him. He is a player that can break the lines, and we’ve been missing that type. So I’m happy he is back.”
