Frank Lampard replaced Graham Potter as the Chelsea interim boss.
The Blues legend was appointed as the Chelsea head coach for the second time until the end of the season.
The club has lost all three games since his appointment against Wolves, Real Madrid and Brighton.
They are currently languishing 11th in the Premier League standings securing only 39 points from 31 games.
Man United legend Roy Keane believes Lampard would need the luck to turn fortunes around at Stamford Bridge.
“Frank is a lucky boy,” he said. “Frank has had some really good jobs, you need some luck in the game, but to go back in there?
“Good luck to him. The way things have changed in football, the manager is under a lot of pressure now. “They’ve got some excellent players, but obviously something is missing at the moment. Even in the last couple of performances, they’re not finding a way to win.
“I look at the personality of a team when all the stats are positive in terms of possession and chances created, but they haven’t got that nastiness that some of the Chelsea teams have had over the last few years.”
