Lampard: Chelsea fans will give Mourinho great welcome back
Lamps says the Special One deserves a special reception for his first game back at the club he guided to Premier League titles in 2005 and 2006.
Midfielder Lampard, 31, said: "I'm sure Jose will get a fantastic reception. He's the most successful boss in the club's history and our fans will want to pay their respects.
"I've seen the warmth and respect that exists on both sides between Jose and Chelsea.
"But once the game starts our fans will want us to beat him. The tie is in the balance and it would be naive for us to say we're favourites. Inter are no mugs and they'll come to London with a 2-1 lead to defend, which allows them to play on the counter-attack.
"We had a lot of possession and shots in the San Siro on Wednesday but we can't go too attacking in the return leg as that may suit their style."
