Liverpool hero Phil Thompson says Mohamed Salah must guard against second season syndrome.

Thompson has offered a word of caution to the 25-year-old.

"Obviously all the comparisons to Lionel Messi are being made because of that low centre of gravity and the way the ball sticks to his left foot, but Messi has obviously delivered consistently at the highest level," he said.

"We've lauded it on Salah but greatness is something that comes over the seasons and it will maybe be harder next season as defenders get wiser to him.

"There's been a lot of players who have second-season syndrome, so it will be interesting to see if he hits the ground running after the summer."
