Watford's Championship rivals have been left angered by a transaction involving defender Hassane Kamara.
The centre-half has been sold to Udinese but immediately loaned back to the Hornets for the remainder of the season. The Italian club are owned by the Pozzo family, who also own the Vicarage Road outfit. Kamara moved for £16m - some £12m more than he was signed for in January.
He will also be playing his football in England's second tier for the foreseeable as the top brass at Watford utilise their ownership of two clubs effectively. The move does not breach any EFL or UEFA rules covering multi-club ownership.
