The Hornets have quietly gone about their business under new boss Walter Mazzarri, losing just one of their last six in the Premier League to place themselves firmly in the top half.
Sunday sees them host Stoke and a victory will only help close the gap on the European places.
Pereyra was one of a raft of new faces to arrive at Vicarage Road in the summer, having been deemed surplus to requirements at Juventus.
The playmaker admits he is happy at the club and believes Watford could push for the top six if they manage to maintain their current form.
“I am happy with what I am achieving at Watford. I have a coach, Walter Mazzarri, who has full faith in me,” Pereyra is quoted as saying by WD Sport. “I am in good shape both physically and psychologically, plus I have a couple of objectives to achieve.
“We’re taking it one day at a time, but we could have our say for the Europa League places.”
Having netted last week against Leicester, punters may choose to use their free bet to back Pereyra to find the net again against the Potters.
