Watford boss Nigel Pearson is wary of asking too much of new arrival Joao Pedro.
The Brazilian met manager Pearson and the Hornets' squad on Thursday morning after completing a much-anticipated move from Fluminense which was agreed in October 2018.
"Hopefully he will have a positive impact," Pearson told the club website.
"It's important for him to settle in and it's important we don't heap too much pressure on a player of such young years.
"We know he is keen to get started and I'm sure he'll get a warm welcome and get support from the players and the club.
"Let's concentrate on the first-team squad who need to go out and find results in the meantime.
"We are pleased to have him here and it's important we don't heap too much pressure on a young player."
