The midfielder knows the task awaiting us at Vicarage Road in this fourth round encounter.
Watford's home form has been impressive of late and an unbeaten run of seven matches stretching back to October was only ended by in-form Reading last time out on January 14.
Jake was on the wrong end of a 2-1 defeat against the Hornets during his spell on loan at Ipswich Town last season.
"It always a difficult place to go," said Jake, who has now featured 24 times for us this season, including starting at right-back in the 3-0 win against Cheltenham in round three.
"They've a good side, plenty of good professionals and they will be well up for it, but so will we.
"We're all determined to do well in the FA Cup. Every player wants to go to Wembley and to go there with Tottenham would be brilliant."
Jake's latest appearance was as a substitute in the final half-hour of Sunday's agonising 3-2 defeat at City.
Indeed, he set-up our glorious late chance when his pass released Gareth Bale, who then squared for Jermain Defoe in front of goal, but the striker couldn't reach it.
We all know what happened after that...
"It was disappointing, but we were all proud of the way we played," added Jake. "we deserved more than we got and we did ourselves justice out there."
The gaffer has been great for me, giving me game time and he's not been afraid to put me on in the big games. I started against United, got a run out against City at home and Arsenal, started at Newcastle, then City again. I've been well pleased in that respect.
