Scott Brown insists the Celtic players will give absolutely everything in their opening Europa League group stage match this week.
The Hoops take on Spanish outfit Atletico Madrid at the Vicente Calderon Stadium on Thursday and Brown says there is an enormous desire to do well in Europe's second tier competition.
"It's definitely going to be a tough one but we want to be in Europe and play in big games like this," he told the club's official website.
"It's going to be a big game for us, especially going over there for the first game. We're going to take it as it comes. Whatever happens happens, but we're going to treat it as one our biggest games of our season so far.
"Atletico signed some quality players but we're a quality team as well. We'll need to defend strongly from the first minute and then see where we go from there."
And Brown added that having the Old Firm derby with Rangers on Sunday will not have a bearing on how the Celtic players go about things in Madrid.
"That's why you sign for a big club like Celtic," he added. "It's a major occasion and be a big stepping stone for Sunday."
