Gigi Buffon concedes Juventus are being shown up at Champions League level after last night's 2-0 defeat to Bordeaux. Fernando and Marouane Chamakh struck for Bordeaux in the second-half to secure the three points for the hosts.

"It's not a tactical issue, it's more one of mentality and the fact there is a big difference between playing in Italy and in Europe," rapped Buffon.

"Here you need physical strength and a bit of quality, but in Europe everyone is very organised and you risk some costly slip-ups.

"We saw with Inter that if you don't have a truly strong organised system, you won't be able to dominate teams on your travels.

"The only Italian side who can do that are Milan and that's why they traditionally do so well in this competition."

The Bianconeri will still qualify for the knockouts if they avoid defeat against Bayern Munich in the final group game in Turin.

"Against Bayern we must try to find a strong core and reduce the risks to a minimum. Up until tonight we had the best defence in the Champions League, so we should be able to achieve that," added the goalkeeper.
