A comfortable Premier League campaign free from relegation fears and an FA Cup semi-final weren't enough to keep Quique Sanchez Flores in the Vicarage Road hot seat. No sooner had the season ended and he was out the door, replaced by the former Inter, Sampdoria and Napoli manager Walter Mazzarri. While Flores did what was expected of him last season, at least in our eyes, the new Italian coach will be expected to eclipse that to appease the Pozzo family.

Business so far

Appointing the 54-year-old Italian on a three-year deal isn't the only bit of early business the Hornets have wrapped up. While neither club is yet to officially confirm the move, Liverpool starlet Jerome Sinclair will join Watford on July 1, as recently confirmed by his management company. The 19-year-old forward, who is the Merseyside club's youngest ever player, will arrive presumably with assurances over an immediate first-team role, given his reasons for leaving Anfield.

Elsewhere, Ben Watson has penned a one-year extension, keeping him at the club until 2018. Abdoulaye Doucouré, who became the club's £8m ($11.5m) record transfer in January, will link up with his new teammates this summer following his loan at Granada. Venezuelan sensation Adalberto Peñaranda will also arrive following his January deal. Nathan Ake meanwhile has returned to parent club Chelsea.

What they need

A dynamic, creative midfielder who can take some of the burden off Troy Deeney and Odion Ighalo and chip in with a few goals wouldn't go amiss. Watford were utterly reliant on the two last season and, when they were off form, goals came at a premium. Watford's shifted from three at the back to four at the back last season. Whatever Mazzari opts for, improvements at full-back positions are also needed.

Who could join

Sinclair could be joined at Vicarage Road by another spurned Liverpool youngster if some reports are to be believed. Jordon Ibe has featured sparingly under Jurgen Klopp and may push for opportunities elsewhere. As is the case when a club appoints a new manager, talk of a reunion with a former player swiftly follows. In Watford and Mazzarri's case, it is Christian Maggio, the right-back who was a regular under the new Hornets boss at Napoli. Gaston Ramirez, released by Southampton, has also been linked but Middlesbrough, where he spent last season on loan, are likely to be considered favourites.

Who could leave

Matej Vydra returns to the club after a fairly unremarkable spell at Reading. The options Mazzarri will have in attack next season could mark the end of his spell.

What the club have said

"Walter has been the target of a number of approaches for his services, so we're delighted to secure him as head coach here at Watford," said CEO Scott Duxbury.

"We're thoroughly looking forward to working with such a highly-regarded coach, with the progress and development of the club always remaining the highest priority."
