Watford have signed former Leicester City goalkeeper Ben Hamer, while left-back Adam Masina has moved to Italian club Udinese for an undisclosed fee.
Meanwhile, 28-year-old Masina signed a three-year deal with Udinese, who finished 12th in Serie A last term.
He joined the Hornets from Bologna in 2018 and scored three goals in 90 league and cup appearances.
Masina played for Italy at under-21 level before switching to Morocco, the country of his birth, and he has so far won 16 international caps.
For Hamer, Watford are the 12th club to call on the goalkeeper during his 22-year career, which started at Reading.
