Watford's capture of Diatta has been welcomed as a positive piece of business, but according to BBC Radio 3CR's Geoff Doyle, the Hornets still have work to do in the transfer market, with a midfielder reportedly identified as the priority area for reinforcement.
Doyle's assessment, shared via BBC News, suggests the club's recruitment hasn't finished despite the new arrival, pointing to a gap in midfield that needs addressing if Watford are to strengthen their squad further this window.
No specific targets or timelines have been mentioned, so it remains to be seen who the Hornets might turn to next.
