John Hartson believes Neil Lennon has calmed down a little, and the results are showing in his side"s performances. the Welsh striker is also more than happy to see Snoop Dogg at Celtic, as long as he gives Neil Lennon "millions and millions of pounds" for investment in players.

Hartson spoke with Newstalk Breafast"s Oisin Langan this morning and he discussed what Celtic have done differently this year to enjoy such unexpected success in the Champions League.

The Scottish champions travel to Lisbon tonight to face Benfica knowing a win will see them qualify for the last 16, while a draw will leave them needing, at most, a draw from their final game of the group- at home to Spartak Moscow next month.
