However, Spurs are managed by cup specialist Juande Ramos and could yet provide an upset.

Here PA Sport takes a look at how the teams compare.

AVRAM GRANT v JUANDE RAMOS

The way Grant has quietly and seamlessly taken over from Jose Mourinho with very little fuss and no loss of form has to be applauded. However, he lacks the presence of his predecessor and has yet to prove he is a winner, although he had modified Chelsea's style slightly to make them less rigid.

Ramos has built a reputation as a knock-out specialist having guided Sevilla to back-to-back UEFA Cups prior to his arrival at White Hart Lane and may yet have a surprise in store for his opposite number. Has made some tough decisions already and is not afraid to risk upsetting individuals, while also getting the absolute best out of players like Jermaine Jenas.

PETR CECH v RADEK CERNY

Cech has long been regarded as the best goalkeeper in the world but his form has taken a slight dip in the last year. However, he remains a formidable figure, gives opponents very few chances and has experience on his side.

Cerny was thrust into the limelight when he became first choice after former England number one Paul Robinson was dropped by Ramos after a number of unconvincing displays. He has handled the promotion well but the real test will come with the Wembley occasion.

FRANK LAMPARD v TOM HUDDLESTONE

Lampard is another Chelsea player to be on his way back from a dip in form and fitness. His goalscoring exploits from midfielder are legendary but probably needs a few more games to get back to top form.

Huddlestone is Spurs' utility man, the enforcer in midfield who is sometimes required to drop back to fill holes in defence. He is a considerable talent but remains unproven at the highest level.

JOE COLE v ROBBIE KEANE

Much of Chelsea's attacking invention comes from the England midfielder, who has made the wide left position his own at Stamford Bridge despite being right-footed. Clever on the ball and with an eye for goal, he has become more important in Lampard's absence.

Keane has a box of tricks at his disposal; quick, a sharp finisher and capable of taking the game to opponents. The Irishman is the man Spurs look to for consistent goals.
