Chelsea fans know the story too well at the moment. The Blues’ transfer model since Roman Abramovich has taken over has worked, giving them their greatest success at any point in their history.
But that doesn’t mean that some players haven’t slipped through the net.
Mohamed Salah is also another former Blue lighting up the Premier League this season. Like De Bruyne, he was written off as a Chelsea flop, but has returned to England much better than before, with 22 league goals so far this season for Liverpool and we’re only in February.
