Watford assistant sporting director Valon Behrami says the decision to replace head coach Paulo Pezzolano with former boss Javi Gracia was "much needed".
The Hornets sacked Pezzolano on Wednesday, just 10 games into his tenure, despite having enjoyed a recent upturn in results in the Championship.
Watford had claimed seven points out of nine across their past three league matches to put them just three points outside of the top six in 11th place.
But despite the side beginning to find its feet, Behrami confirmed that "language was the barrier" for the Uruguayan.
