CHELSEA v INTER: Where The Stamford Bridge Battle Will Be Won And Lost

It's the one football fans, most especially Chelsea followers, have been waiting weeks for - the return 'home' of the Special One, and the visit of Inter Milan, who stand in the way of Chelsea and a place in the Champions League quarter-finals. It's sure to be an incredible night down at the Bridge, with the emotions running high as Chelsea welcome back the most successful manager in their history. Jose Mourinho is guaranteed to get a hero's reception on his return to West London, in recognition of the back-to-back league titles, FA and Carling Cups notched up in his three-year reign. The way in which he left the club, in September 2007, meant the supporters never got the chance to say goodbye, or a proper thank you for all his success, so tonight will see an outpouring of gratitude from the Stamford Bridge terraces to the former manager. However, once that first whistle is blown, Inter and Mourinho will be opponents, and Chelsea has got a great chance of making the last-eight once again. All eyes on the prize, as they say, once the game is underway. There are 3 key areas to watch in this match and which arguably can decide the game. 1. ESTEBAN CAMBIASSO v NICOLAS ANELKA: Argentina international Esteban Cambiasso will be charged with breaking up Chelsea's attacks. The defensive midfielder is deployed in the holding role that Coach Jose Mourinho favours. Anelka is more than likely to find himself playing just behind main striker Didier Drogba and that will put him up against the combative 29-year-old. Anelka has enjoyed a superb season so far for the Blues but the France international will have to be at his very best to win this personal. 2. SULLEY MUNTARI v FRANK LAMPARD: Mourinho tried to sign Lampard from Chelsea when he left Stamford Bridge but having failed in his attempt to lure the Englishman away from his former club, the 'Special One' went for next best thing - Pompey's Muntari. The pair have not always seen eye-to-eye at Inter but Mourinho certainly rates him as a player. Hard-running, with flair to match his engine, Muntari will provide Lampard with a stiff test. 3. GORAN PANDEV v JOHN TERRY: Terry, at fault for both goals in the 2-1 defeat against Everton in the Barclays Premier League earlier this month, will have to be back to his very best to cope with 26-year-old Macedonia striker Pandev. He signed a five-year deal with Inter last month after having his contract with Lazio terminated. He made an instant impact and if Terry is still feeling any effects of his off-the-field problems, then he will find little sympathy from Pandev. Meanwhile, Manchester United manager Sir Alex Ferguson has admitted Tuesday night�s Champions League clash between Chelsea and Inter is hard to call, but feels Blues� striker Didier Drogba may prove the difference between the two sides. The last-16 tie is intriguingly poised with the Italian champions bringing a 2-1 lead to Stamford Bridge, yet having grabbed an away goal Chelsea will feel confident they can also progress to the quarter-finals of the competition. Meanwhile, Ferguson predicts it will be a very tough game for the hosts particularly against their tactically astute former manager Jose Mourinho. �Inter versus Chelsea is a real big one. Chelsea are hard to beat at Stamford Bridge but it is a good Inter team - an improved Inter team and Jose [Mourinho] will have them well organised,� he told the Sunday People. �It won't be an easy game for Chelsea. I think Jose has Inter playing now as he wants, it's his team. He has changed the system and they are not bad.� The Scot then moved on to highlight how Drogba could make the difference and explained how his brute strength could cause chaos in Inter�s rearguard. "For me, it will rest on how they handle [Didier] Drogba. They don't have a great deal of height at the back...They have Lucio, who is a reasonable size, but [Walter] Samuel is not big,� he added. "He's only about 5ft 9ins or so. He's tough, but not particularly big, so Drogba's size could be a problem."
