Juan Mata says Frank Lampard has made sure his Chelsea team-mates are well-informed over the club's bitter rivalry with Leeds ahead of their Capital One Cup clash.

Having let four pieces of silverware slip through their fingers already this season, Chelsea's young guns are in danger of becoming a generation of also-rans. Lampard, who returned to captain the side on Sunday following what has been an injury-hit 2012, is a proven winner and bristled at suggestions more recent recruits did not possess the same mentality. The midfielder, who declared himself fit enough to start again at Elland Road, said: "You can't go and win every tournament every year. "We've never done that. No-one does it. "We've changed the personnel a bit this year and there's been a bedding-in process and we've changed the manager, so there's been quite a few circumstances this year. "We just have to try to improve and play better, simple as that."
