The Hornets boss feels the Senegal international is close to playing a prominent role for his side against the Reds
The winger suffered a hamstring problem against Tottenham Hotspur in January which sidelined him from action, missing his side’s defeats against Aston Villa, Tranmere Rovers, Everton and their draw against Brighton and Hove Albion.
Ahead of their clash with the Reds at Vicarage Road, Pearson stated the forward, who has recovered well from his injury, could be handed a starting role in the encounter.
“[Sarr] is much closer [to start]. The squad’s had a good week,” Pearson told the club website.
Sarr has made 19 appearances, scoring four goals and providing three assists since teaming up with the Hornets from French side Rennes last summer.
Watford are one place above the base of the Premier League table after securing 24 points from 27 games.
