Slot is eager to see Salah stay at Anfield but hinted that it might take more than just financial incentives to convince the 32-year-old to commit his future to the club.
"Maybe for the one that has to pay him it isn't the best but for everyone else, it is the best because if you want to play at this club you need to be at his level otherwise you are almost useless to play at this club," he said. "We only need players that are at the top of their game because this is one of the best if not the best club in the world to play for. He needs to have these performances to play here and hopefully to extend here."
