Watford completed a new club record transfer following the August 2019 deadline day arrival of highly sought-after Senegal international Ismaïla Sarr.
The Hornets beat off strong competition to secure the services of the 21-year-old winger from Rennes, who agreed a five-year contract with the Hornets.
A Coupe de France winner with Rennes and an AFCON runner-up for Senegal, the exciting attacker started out with Metz before earning a move to fellow Ligue 1 side Rennes in 2017.
He played 77 times over two years at Roazhon Park, scoring 18 goals, including some eye-catching displays against Arsenal in the Europa League earlier this year.
The pacey forward appeared three times at the 2018 World Cup for Senegal and then played regularly throughout the Lions’ run to the AFCON 2019 final.
