Inter Milan boss Jose Mourinho insists he should not have been sacked by Chelsea, stoking the tension ahead of Tuesday night's Champions League last-16 tie in London.
Italian champions Inter hold a 2-1 lead after winning the first leg in the San Siro, with Mourinho making an emotional return to the club where he is still adored by fans after winning two English Premier League titles despite his acrimonious departure in 2007.
The Portuguese coach was axed by Chelsea's billionaire Russian owner Roman Abramovich just two months into the season following a disappointing 1-1 draw with Norwegian club Rosenborg in the Champions League.
He led Inter to the Serie A title in his first year in charge and the Nerazzuri top the Italian table again this season, though their lead has been cut to one point following Friday's shock defeat by Catania.
