Emma Hayes doubts there is much to learn from Arsenal's 5-1 demolition job of Lyon earlier this season ahead of Chelsea's clash with the European champions. 

The Gunners laid down a marker in the Champions League last October with a stunning win over a club that have won the competition in six of the last seven seasons. 

Lyon gained a measure of revenge at the Emirates Stadium in December to finish runners-up in their group behind Arsenal, with the French side's reward a quarter-final showdown with Chelsea. 

The teams met in a pre-season friendly back in August, when Chelsea squandered a two-goal lead to draw 2-2 before losing on penalties. 

And they will collide again in Wednesday's first leg at the Groupama Stadium with Lyon a much stronger prospect thanks to a number of big names back in action after injuries. 

Asked whether there was anything Chelsea could take from Arsenal's win earlier in the season, Hayes said: "It was a phenomenal performance from Arsenal but we also saw Lyon go there and win 1-0. 

"We know Lyon are a top side. Earlier on in the season they were missing a lot of players, that's not the case now, they have a lot of their experienced players back. 

"There are certainly things from Arsenal's performance that night that reminded us of some of the things we repeated in the pre-season game against Lyon. 

"But I think this is a much different game and Lyon are at a much different stage than they were earlier in the season."

Both Chelsea and Lyon top their respective domestic divisions and many anticipate a showdown between two in-form teams may be a nip-and-tuck affair. 

Hayes added: "Both teams will be working each other out, particularly in the first half. I think both ties will be very different. 

"I don't know what it's going to look like, what I know is we've prepared the best we can and we're absolutely ready."
