Steve Bruce has revealed Kenwyne Jones' inconsistency was the primary reason Sunderland allowed him to join Stoke City.
Bruce has acknowledged the Trinidad & Tobago man is a talented striker, but felt he failed to perform at his best regularly for the club.
Jones completed his £8million move to Stoke on Wednesday, eclipsing the Potters' transfer record in the process.
Bruce admits that with things not going to plan for Jones at the Stadium of Light he was happy accepting Stoke's offer.
"There has always been a frustration with me, and I think with supporters who have watched Kenwyne, that you see an abundance of talent but it has not come out often enough for us for whatever reason," he told the Sunderland Echo.
"In management you get paid to make some important decisions sometimes. Stoke have been badgering me for a year.
"Everyone knows they love a big, traditional centre-forward and he might go and suit them.
"Towards the end with Kenwyne, things were not working out so I have accepted Stoke's offer."
