Dimitar Berbatov has warned Fulham to learn from their Premier League mistakes as they mount a promotion charge this season.
Fulham have become something of a yoyo club over the past four seasons, where they have either been promoted to the top flight or relegated to the Championship.
New boss Marco Silva is overseeing a fast start this campaign, with the Whites commanding the top spot before recent defeats by Reading and Coventry.
Promotion is the priority at Craven Cottage this campaign, but former Fulham striker Berbatov says the club must learn from past mistakes if they are to go up this season.
"That's something that hasn't surprised me," Berbatov said of Fulham starting the season brightly, in an interview with Mirror Football.
"But Fulham need to learn. They are doing the hard work, fighting promotions, then going to the Premier League, then getting relegated, then promoted, then relegated.
"It's strange, I am watching them and I'm like 'Guys, come on! You've done it twice now'.
"If you do it a third time, get promoted and relegated again, then something is not right. Maybe you don't belong to the Premier League.
"Fulham are starting the season in great form but we know the Championship and how many games there are ahead of them.
"I wish them luck, I wish them to get promoted and I wish from the bottom of my heart that when they get to the Premier League they fix their defence and stay there.
"The club is great, it has a great training ground, I love the club, and it's a great place in London. So please stay in the Premier League when that moment arrives."
