"We can't think about that because we know how difficult it is to win the Champions League. There are still eight other great sides in the competition.," says the boss.
"We must keep our feet on the ground. It's going to be a very difficult task, whoever we get in the draw.
"I'd prefer the players to forget about the Champions League for now and concentrate only on the Premiership.
"If we do the same things in the Premiership as we have in Europe, we will have a good chance of finishing in the top four and qualifying again."
