Watford boss Brendan Rodgers faces an FA Cup fifth round tie against former club Chelsea.
The 38-year-old will not be the only familiar face for the visitors with Frank Lampard Sr, father of Chelsea's England midfielder, currently employed as Rodgers' football consultant.
Captain Jay DeMerit, who netted his first FA Cup goal in Saturday's 4-3 fourth-round win over Crystal Palace, believes the occasion will be one for the Hornets to relish.
He told Sky Sports: "It's a tough game of course but this is what we play for. Ever since I've been here we've never been short of cup runs and it's always good to get in these situations."
