The Bulgarian played under the Italian at Monaco and feels he can keep the Cottagers in the Premier League after taking over from Slavisa Jokanovic
Dimitar Berbatov has praised Fulham for the appointment of Claudio Ranieri and believes he is exactly what the club need to survive in the Premier League.
Ranieri has replaced Slavisa Jokanovic at Craven Cottage following a disappointing start to the season which has left them bottom of the table with just five points from 12 games.
Berbatov, who played under Ranieri at Monaco, is confident the former Chelsea and Leicester manager has what it takes to keep Fulham in the top flight.
"Ranieri was my coach at Monaco so I know him well, and I think if you appoint someone in this situation, with Fulham are last in the table, you want to appoint someone with great experience who could help them stay up," the former Fulham striker wrote in his Betfair column .
"He is a great appointment, I wish him luck and I know he's going to work hard, because that's what he does."
Berbatov also believes that Ranieri could get the best out of Ryan Sessegnon, with the 18-year-old having only scored once so far this season.
"When I was under him at Monaco, there were so many young players there like Martial and James Rodriguez,” added Berbatov.
“All these talented footballers with potential and he was working well with them. Ranieri has that experience, he knows how to handle not only young talent but the big names too."
Although Berbatov is impressed with the appointment of Ranieri he feels the sacking of Jokanovic was premature, despite a run of six consecutive defeats.
He said: "it's a bit unfair for Jokanovic to go. Look at Newcastle, for example, they didn't win a game for 10 matches in a row and now they've won back-to-back games."
Berbatov was impressed with Jokanovic's management style as he believes Fulham should not stray too far from the possession-based approach he brought to Craven Cottage during his tenure.
"They play good football and this is what I like about them.
“I watched them against Liverpool and they don't just kick the ball to see what happens next, they pass around the ball well.
"Sometimes this won't give you results because of the teams you face in the league are of better quality, or you have bad luck like their disallowed goal against Liverpool. However, the results will come if you stick to your philosophy."
