The 29-year-old Spanish international spoke to the club’s official website after the 2-0 win at Stevenage on Thursday evening.
“Every day I feel better. We are working hard in double sessions to understand the coach’s concepts and ideas; we are improving every game," he said.
Suarez also spoke of his delight at being able to play a full part in Watford’s pre-season preparations, something he failed to do last summer at Fiorentina.
“I’m happy to do a full pre-season. Last year I didn’t, this year will be different and I’m working hard to get myself in shape.”
The Spaniard also spoke of the difference in the pace of the English game by paying tribute to the opposition on the night; League Two side Stevenage. “It’s hard, even today, we played a hard team. It doesn’t matter who you play, we know that," with him clearly learning plenty from pre-season already.
Étienne Capoue and Jerome Sinclair both notched their first ever goals for Mazzarri’s men in the victory at Broadhall Way. However, Suarez doesn’t think that the results during pre-season are crucial.
“We want to win and we want play to win, but we also need to get fit," he asserted. "There’s still one month until the start of the Premier League, so we have to keep working hard.
“The most important thing now is getting minutes, and understanding the ideas of the coach and the system he wants to play.”
Ready for the Austrian trip
Suarez and the rest of the Watford group will now turn their attentions to a one-week training camp in Austria. During the trip they will take on German side Union Berlin as well as Russian outfit Anzhi Makhachkala.
The Spaniard knows it will be "a hard week," but concedes that "that's pre-season.
"We work hard and that’s what we are doing now, and we have to continue like this and be ready for the beginning of the Premier League.”
