Frank Lampard insists the best is yet to come from his young Chelsea side as they face a crucial Champions League showdown in Valencia.

The Blues arrive at the Mestalla on Wednesday night knowing victory will seal their place in the knockout stages courtesy of a better head-to-head record against the La Liga side and Ajax.

However, defeat combined with an Ajax win over Lille will take their destiny out of their hands but Lampard believes Chelsea will thrive under the pressure of securing what would be their third away win in the competition this season.

“I believe in the group and I believed in their ability to go to Lille and Ajax and get results,” he said. 

“The character we showed to come back against Ajax at home [drawing 4-4] was another small step for the group. It hasn’t surprised me. But I know there’s more to come.”

Lampard, however, warned his squad of the raucous atmosphere that awaits them, having represented Chelsea here as a player, most recently during the group stage in 2011 when he scored in a 1-1 draw as part of a campaign in which the Blues eventually went on to lift the trophy.

“I watched a lot of Valencia’s matches,” he said. “Not just in the Champions League but in La Liga and we have the experience of playing against them.

”So, I expect a very organised team, a team with a lot of quality, a lot of quality in attacking areas with the two strikers and the wide players that they have. 

“My feeling having played in this stadium, it is not just the team it is the support and the atmosphere that come together. When they are playing well, the atmosphere is very strong then it is a difficult game for everybody so I expect a difficult match.”

Valencia have won just five of their 13 matches in all competitions since beating Chelsea 1-0 at Stamford Bridge on September 17.

“My major feeling after the first game was the lesson will always be, whether you’re 18 or 32, in the Champions League if you sleep for one moment you can lose a game at this level,” added Lampard. 

“That was the lesson in the first game. Since then of course we’ve shown moments where we’ve gone to Lille and Ajax and got results at tough places.”
