Liverpool forward Sadio Mane has warned team-mate Andy Robertson he'll need help defending Senegal compatriot Ismaila Sarr, who would "kill" him for speed if given the space.
Sarr, 21, joined Watford from Rennes for a club-record fee of £30 million on the Premier League's transfer deadline day.
The youngster has already been capped 21 times for Senegal, and Mane told The Athletic's Adam Leventhal (h/t Goal's James Westwood) he'll need to offer Robertson additional cover when going up against his compatriot:
“The first day [Sarr] signed I sent him a message to say good luck and that I was happy for him.
