The Chelsea boss has hit back at the Italian coach after claims that the Portuguese won the Champions League with a team that had already been prepared by the now-Galatasaray boss
Mancini, who was in charge of Inter for four years until Mourinho replaced him in 2008, had insisted that the Portuguese won the Champions League because he took control of a "good team" that the 49-year-old had built during four years with the Italian club.
Although ahead of Wednesday's Champions League last 16 clash between Chelsea and Galatasaray, the Blues boss hit back at the former Manchester City manager, claiming that he left him with no more than a five-a-side team at San Siro.
He said: "It's funny because my team in the [Champions League] final had Lucio, [Thiago] Motta, [Diego] Milito, [Samuel] Eto'o, [Goran] Pandev and [Wesley] Sneijder.
"From 11 players, he didn't work with six of them. So he made a five-a-side team because I played with only five players from his team."
Chelsea head to the Turk Telekom Arena on Wednesday night looking to secure their eighth win in the competition this season ahead of the second leg of the tie on March 18.
