Michael Carrick says Manchester United mustn't get carried away with their 100 per cent Champions League record.
"Obviously, we will now have to wait and see how the draw goes but we realise the biggest tests are still to come and we will need to be at our best when the competition starts again after Christmas."
The Geordie added: "Winning is such a nice habit to get into and we have managed to do that of late.
"We had a bit of a blip on Saturday but these things happen.
"The same kind of thing happened last season, it is how you bounce back that counts.
"We have managed to bounce back immediately with a win and hopefully we can carry it on."
