Celtic goalkeeper Craig Gordon is expecting a tough test when his side pay a visit to Red Bull Salzburg in the Europa League tomorrow evening.
The former Sunderland stopper believes that the Hoops will be up against "a great team" when they travel to Austria for their Group D opener.
"They are a great team. They press high up the pitch then try to force teams into mistakes. They have done very well in their domestic league in recent years so we know we are in for a big fight and a very difficult match," Sky Sports News quotes Gordon as saying.
"But we're here to get points on the board and get off to a good start in the competition. We have to be solid and concentrate on what we do well and we will have to defend very well."
Celtic also share Group D with Dinamo Zagreb and Astra Giurgiu.
