Celtic play their second match in Champions League Group B this evening when they take on Anderlecht in Brussels.
Brendan Rodgers's side lost their opening fixture to Paris Saint-Germain at Parkhead a fortnight ago while the Belgians went down to Bayern Munich, who Celtic face in a double header on matchdays three and four.
Rodgers, whose team beat Rangers 2-0 at Ibrox on Saturday, told the club website: "Obviously confidence is high and the players in good condition so we are looking forward to the game.
“This is a game both teams will be looking at to have that realistic chance of playing in Europe after Christmas but all games at this level are very tough and we have obviously experienced that in the last couple of seasons."
