We continued our fine form in the Capital One Cup on Tuesday night as a 4-0 victory made it eight wins in nine and just one goal conceded in all competitions this season.
Andre expects our fourth game in nine days to test that defensive resolve to the limit.
"We come into this game on the back of good results so far but now we face a different proposition, a different team in style with great players and it won’t be easy," he said.
"We’ve looked solid at the back, very focused and it's not just the clean sheets, but the amount of opportunities we’ve allowed and the chances we’ve prevented from opponents.
"Again, this is a completely different proposition on Saturday, a team that will have more chances, but we have to show our ability to be solid at the back again."
Much has been made of Andre's previous work under Jose Mourinho's management, but he insisted that would count for little preparing for Saturday's match. "I don’t think it’s any advantage, we prepare to play Chelsea, not Jose Mourinho," he said.
"They have made some improvements, so they are stronger than last season. We have made them as well and we look good. You would expect a tight encounter.
"Above all, we have a great team spirit and motivation for this game and that can make a difference."
