And continues to actively operate in the market and has already acquired the eighth football player this summer - a four-year contract signed with defender John O'Shea.
The 30-year-old Irishman followed the example of his teammate Wes Brown, who signed with "Sunderland" the afternoon before.
A few weeks ago, the Manchester club agreed to sell O'Shea, Brown, and midfielder Darron Gibson for a total of 14 million euros. The future of the latter remains unclear, as "Newcastle" is also interested in him.
"John has been a solid and consistent player for Manchester United over the past decade, which shows the experience he has accumulated," said "Sunderland" manager Steve Bruce. "O'Shea is a true professional both on and off the field.
I am very pleased with the players we have managed to acquire for the next season."
The "Sunderland" squad was supplemented by the "Birmingham" duo of midfielder Craig Gardner and midfielder Sebastian Larsson, young "Ipswich" forward Connor Wickham, South Korean national team forward Ji Dong Won, and "Coventry" goalkeeper Kieren Westwood. The opportunity to buy out the contract of Egyptian full-back Ahmed Elmohamady, who was loaned to the English team last season, was also taken.
