Watkins was speaking after Tuesday's defeat at Manchester City.
"We have to move on to the weekend now, focus on the FA Cup and a big game at Wembley,” said Watkins. “We all want to win a trophy so all eyes on that.
“I think this is the furthest we've got in the FA Cup since I've been at the club. We've always gone out quite early doors and it's disappointing. You want to win these competitions and it's nice that we're in the latter stages of it.
“I’ve been saying to the boys one thing I set my eyes on when I joined the club was winning a trophy. It’s been so long since the club has done that and that’s the main aim, so Saturday is massive and we will be doing all we can to get to the final.
“Obviously, Palace have been a bit of a bogey team for us, but on our day we’re capable of beating anyone and everyone is looking forward to that, so just bring on the weekend.”
