There has been a serenity about Watford in this transfer window, with players arriving to add depth and resolve long-standing issues at Vicarage Road.

A new left-back in the form of Adam Masina, the youthful potential of Ben Wilmot, Gerard Deulofeu's creative spark and the reliable Ben Foster have all been brought into a side fast taking shape.

Ken Sema and Marc Navarro have also rocked up at WD18 to provide a sense Watford will head into the Premier League campaign in positive mood.

This is not to say the work is done for Javi Gracia and those in charge of the purse strings at the Vic, and there is one glaring area where reinforcements are still needed.

Goals, that oh-so precious footballing commodity, were in limited supply last term and, as always, such shortcomings will see fingers pointed at the strikers.

The Hornets registered just 44 Premier League goals in 2017/18 - only eight teams in the league scored fewer and six of those finished below Watford - and Abdoulaye Doucoure's seven strikers made him the club's top scorer.

In the cold light of day, none of Watford's strikers could claim to have had a good season and failing to react to their struggles would represent a big oversight which could undermine Watford's hopes next season.

Record £18.5 million signing Andre Gray toiled, scoring five goals, and Gracia often favoured the physicality of Troy Deeney and Stefano Okaka after taking over in January.

Okaka made a concerted effort to leave the club in the winter and there is no guarantee he will remain, while Deeney still needs to convince he can recapture the fitness levels and form of old.

The Watford skipper was hampered by injury and his own ill-discipline last season and you sense next year will be a pivotal one for a player who is now 30.

Deeney, who underwent a groin operation in the summer of 2017, will doubtless benefit from a full pre-season and it would be foolish to write off a player who has been the Hornets' talisman for a number of years.

Watford's failure to find the net on a regular basis is by no means solely Deeney's burden to carry, and Gracia will hope players such as Deulofeu and Richarlison can contribute more goals from wide areas.

Nonetheless, adding further options in attack should now become the priority before the season gets underway with the visit of Brighton on August 11.

There may have to be some goings before that is a possibility and the incoming of six new names has left Gracia with a bloated squad in need of trimming, and there have been precious few strikers linked with a move to Watford.

So too have reports of a potential departure for Doucoure gone quiet, but both situations could well run until late in the transfer window and the potential income which would arrive with the latter's departure may ease the financial burden of signing a new striker.

What is certain, is that late in the day or otherwise, Watford must move to fill the final major piece in their transfer window puzzle.
