Nicolas Frutos has highlighted Scott Brown and Patrick Roberts as the Celtic danger men.
The stand in Anderlecht boss will be in charge for the third time tomorrow night when the two clubs clash in Brussels.
A win against Celtic could convince the Anderlecht board to give Frutos the job on a permanent basis as well as get them off the mark in Group B.
Brown and Roberts were in outstanding form as Celtic beat Sevco at the weekend and are certain starters in Brendan Rodgers side.
Previewing tomorrow’s match in The Sun Frutos said: â€œCeltic have a very good collective game.
â€œThey are physical but I wouldnâ€™t say itâ€™s a typical Scottish style of play like it was before.
â€œThey have very good players like Roberts and the captain [Scott Brown] who has been there forever.
â€œSo there is a very nice mix between experienced players, a lot of speed up front with some physical force and an organised defence.
â€œThey will work hard and we will have to work hard to do our best to perform.â€�
Celtic flew out to Belgium at lunchtime today after training in the morning at Lennoxtown.
Although neither side will admit it the two clubs are basically in a battle for third place with Bayern Munich and Paris Saint Germain favourites to go through.
After tomorrow’s match Celtic host Anderlecht in Match Day 6, following the match in Brussels Celtic have back-to-back matches against Bayern Munich.
