Manchester United boss Sir Alex Ferguson admits he's a big fan of Villarreal counterpart Manuel Pellegrini.
"Manuel Pellegrini is in his fifth season at Villarreal, which is a long time in Spain," reflected Ferguson.
"In that time they have been second twice and will be a very difficult team to beat, while Celtic's home record is as good as anyone's in Europe.
"We are certainly not taking any chances and I will stick to what I always say. Give me 10 points and I will see you in February."
