Manchester United manager Louis van Gaal feels sorry for the plight of his "friend" Dick Advocaat at Sunderland.
The Dutch pair will be in opposing dug-outs at Old Trafford on Saturday, kick-off 15:00 BST.
United are second in the Premier League while Sunderland are bottom of the table with two points from six games.
"Dick Advocaat is a friend," said Van Gaal. "I sympathise with the person. I hope Sunderland win every game except the ones against Manchester United."
He added: "We have seen each other many times. We are calling each other."
Van Gaal, 64, spent two seasons as a team-mate of 67-year-old Advocaat at Sparta Rotterdam between 1980 and 1982.
Advocaat had a better record in managerial meetings when he was at PSV and Van Gaal at Ajax, winning three and drawing five of their nine encounters.
Meanwhile, striker James Wilson has signed a new four-year contract at United, with an option of a further year.
The 19-year-old academy graduate scored two goals on his debut in a 3-1 victory against Hull City in May 2014, but has featured in just two league games under Van Gaal.
Van Gaal said: "James is one of the brightest young English prospects and we are delighted he has signed a new contract."
The Dutchman said on Friday he would wait until December before deciding whether he will send the Wilson out on loan to get further experience.
