Sunday's match is our final assignment before the 2022 World Cup, and Erik ten Hag and his squad will be desperate to finish on a high note, following a setback at Villa Park last weekend.
But Berbatov, who spent 18 months with the west London club between 2012 and 2014, says he's been impressed by what he's seen from the promoted club so far in 2022/23.
And he warns that the Cottagers' home can be an awkward place for away teams to visit, especially if they arrive with expectations of a straightforward three points.
“From my time, I know that, if you're not careful, if you underestimate Craven Cottage and Fulham, you're going to have a problem,” said the Bulgarian legend.
