Also, Tony Watt hits back at 'fat' jibes
Biton has played a part against AC Milan and St Johnstone, as well as starting in the League Cup defeat against Morton on Tuesday.
But Lennon thinks that he will improve with more time on the field.
He told Celtic TV: ‘There is a lot more to come from him. He has only been here a week and it is too early to make any kind of rash judgements on him. We think he is a good player and that he will improve a hell of a lot over the next few months.’
The Celtic boss says James Forrest has recovered from his virus but won’t be available for Saturday’s game against Kilmarnock at Rugby Park, but he thinks he side can bounce back from the disappointing loss to Morton in midweek.
‘We have had a blip, I am looking forward to the reaction I am going to get because we need a good performance going into the game Tuesday.’
Striker Tony Watt, who is currently on loan at Belgian club Lierse, has hit back at claims that he is fat and unfit by taking his shirt off after scoring for the club in the Belgian Cup, according to the Scotsman.
Watt had recently received criticism from manager Stanley Menzo and Watt wanted to show he was in good condition, even if he picked up a yellow card for his troubles.
‘I just wanted to show that I am not fat. I knew perfectly well that if I took my top off I would get a yellow card – it happens all over the world.
‘But I just wanted to show everyone that I am in prime condition.’
Kenny Dalglish thinks Celtic's chances of making the last 16 on the Champions League will rest on the clashes with Ajax.
Dalglish told the BBC: 'The San Siro was a disappointing result but the performance was more than acceptable.
'Back to back with Ajax could determine what happens.
'They then step out of that game into a much easier game against Barcelona'
