Valencia manager Marcelino says Celtic have a number of key man but has also praised their threat as a team.
The La Liga side make the trip to Parkhead on Thursday night, as they face the Hoops in the first leg of their Europa League last-32 tie.
Marcelino’s men are the favourites to make it through to the next round, but they will have their work cut out on Thursday.
A hostile atmosphere awaits them, as Celtic face one of their biggest European nights in years.
Although Marcelino respects Celtic hugely as an all-round team, he did also take time to single out a few individuals he thought would be key, in an interview with the Daily Record:

They have a very important player out injured just now in Kieran Tierney. But I think James Forrest, Odsonne Edouard, Scott Brown are all very good players.
Celtic have a lot of very good players at very high levels. As a team, they work very well. They have a very good manager who has managed Liverpool and they have a very attacking philosophy.
I repeat, they are a very good team, with very good players. I have the feeling that, in the future, some of these players will be playing at a very high level.
Brendan Rodgers has urged his players to attack their opponents on Thursday, hopefully taking a lead with them to Spain when the two sides reconvene next week.
The key players that Marcelino mentioned are sure to be pivotal figures over the two legs.
