The Baggies host the Premier League champion this weekend, with Clarke’s side already being forced to block ticket sales on exchange website Viagogo as many home supporters’ seats are being bought by United fans for the final game of Sir Alex Ferguson's managerial career. Clarke has confirmed that West Brom will pay tribute to the Red Devils and Ferguson in what will be his 1,500th game in charge.
"It's going to be a historic afternoon and I've been involved with so many clubs over the years that have played against Sir Alex," Clarke told reporters. "Everybody has paid tribute to him and he's decided to get out of the game at the right time. The pleasing thing for me is that he goes out at the top, with his team having finished the season as champions.
"But we're not there for a party. We're there for our supporters and we will do our utmost to finish the season on a high."
West Brom currently sits eighth in the Premier League table after gathering its highest-ever tally of 48 points, but the Baggies could drop a place in the league table if they lose to United and Swansea beats Fulham.
