Jose Mourinho believes Manchester City have underachieved since their 2008 takeover by Sheikh Mansour and have ridden their luck this season, reports the BBC.
City won the FA Cup in 2011 and the Premier League in 2012, but have failed to get beyond the Champions League group stage on two out of three occasions, and failed to win anything last season.
“They won one title, won a couple of cups,” said Chelsea boss Mourinho ahead of their game at City tonight.
“The team is fantastic, the squad is fantastic and normally they [should] win more titles.”
City have spent more than £700million on transfer fees since the 2008 takeover, recruiting world class players the likes of Sergio Aguero, David Silva and Yaya Toure.
They have made it to the last 16 of the Champions League for the first time this season, where they face Barcelona in the first leg at the Etihad on 18 February.
“In Europe they didn’t do well, or close to doing well,” added Mourinho. “Speaking objectively, they did very bad in the Champions League in previous seasons, also in the Europa League.
Mourinho has also rejected the claim from Tottenham boss Tim Sherwood that City are the best team on the planet, claiming the league leaders have been ‘lucky’ this season.
“The reality is they have many crucial decisions in their favour,” he said.
“They are lucky,” he added. “The referees, they try to do their best and sometimes they make mistakes and normally during the season the mistakes are split between teams.
“In their case, they have everything in their favour.”
