Sunderland were afforded permission to speak to Grayson by Preston earlier this afternoon, and they have wasted no time in tying him down to a three-year deal which keeps him at the Stadium of Light until 2020.
The 47-year-old ends a four-year spell at Deepdale to take charge of recently-relegated Sunderland and will meet up with his new players and staff tomorrow ahead of a five-day training camp in Austria.
“I am delighted to come to Sunderland, a club with such wonderful history and tradition, and I’m excited by the opportunity to manage this club and I want to bring the good times back,” he told the club’s official website.
“Sunderland are so fortunate to have such tremendous support and I want to give these fans a team they can be proud of. I want a group of players full of desire, team spirit and a never-say-die attitude – that’s the very least that we should expect from a Sunderland player.
“The Championship is a demanding league, but with all the attributes I have highlighted then our aim has to be to get the club back to where it belongs as quickly as possible and I can’t wait to get started.”
