Beppe Sannino believes "heart and adrenaline" helped new Watford signing Daniel Tozser impress during his debut and that the new Watford signing will find his second match more difficult.
The experienced Hungary international had not played a competitive game all season prior to joining the Hornets on loan from Genoa last week.
However, the ex-Genk captain impressed in the holding midfield role on Sunday and was part of a side which largely nullified Brighton & Hove Albion's threat.
After the match, Sannino said: "Tozser gave us some more options in the middle. I am sure the next game will be tougher for him because in the first game you play for your new club, you end up playing with your heart and adrenaline. But as he has not been playing much before today, the next game could be tougher because of fitness. We will watch him in the coming week and work with him."
Tozser started his career at Debrecen and joined Galatasaray in his teens but was unable to break into the team at the Turkish club.
The 28-year-old returned to his native Hungary with Ferencváros and scored four goals in 60 appearances during his two-year stay at the Budapest club.
AEK Athens signed the player in 2006, where he tasted Champions League football for the first time. He made 56 outings and scored three goals during two years at the club.
In 2008 Belgian side Genk reportedly paid around €1.5m to sign the defensive midfielder, who can also play on the left side.
During his four-year stay at the club, he made 159 appearances and scored 22 goals, where he again featured in the Champions League.
Genoa beat a few Italian clubs to sign Tozser in 2012 but after 22 outings last season, he had only been an unused sub on five occasions during this campaign.
