Watford manager Marco Silva has revealed that his midfield is "more or less complete" as he turns his attention to improving the squad in defence and attack.
The Hornets have made four signing so far this summer, as well as securing a permanent deal for Tom Cleverley.
Watford are now rumoured to be searching for a goalkeeper, left-back and a forward, but Silva has refused to specify in which positions he is looking to make additions.
"Good problems and normal problems; it's what I want for the team," he told the Hertfordshire Mercury.
"It's what I expect and it's clear that in the middle zone at this moment we are more or less complete.
"Now we need to do the same in the defensive zone and attacking zone.
"We stay working in the market and after we'll see. I don't want to talk about positions. First I respect our players - of course we want to improve our roster but we need to respect that because we have good players.
"The last two weeks they've worked hard and showed good quality. That's what I want them to do and we'll do our best in the market."
Asked how many players he is looking to bring in before the window shuts in September, Silva added:
"Of course, Gino [Pozzo] and Filippo [Giraldi] know what I want for the team and what I need.
