Manchester United fans have been left unhappy after teenage defender Ayden Heaven was included in the starting XI for their game against Bournemouth. The Red Devils are looking to claim another win in the league, having overcome Wolves in their last game. Ruben Amorim has made just one change to his XI for the visit of the Cherries, having seen his side defeat bottom side Wolves last week. French centre-back Leny Yoro comes into the XI for Noussair Mazraoui, joining Heaven and Luke Shaw in the back three for the Red Devils. Former Arsenal man Heaven is set to make his fifth league appearance of the season, more than he managed in the entirety of the 2024-25 season. The 19-year-old is playing for a third successive game, with both Harry Maguire and Matthijs De Ligt sidelined at the moment. Manchester United fans are unconvinced by the young centre-back, and are skeptical of his inclusion in the XI to face Bournemouth. A section of the fans have taken to X to complain about the defender's inclusion in the line-up.A fan complained about the inclusion of youngsters Yoro and Heaven in the XI.

Manchester United working on plan to combat AFCON absences: ReportsManchester United are reportedly working on a plan to live with the absences of key players during AFCON this month. The Red Devils are set to miss the trio of Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo for parts of the next month. Laurie Whitwell @lauriewhitwellLINKRuben Amorim looking at adapting formation to more like 4-3-3. He told players ahead of Wolves a change would come + work has since been done at Carrington in that shape. "[AFCON] is a good opportunity for us to try to play in a different way." ⬇️ #MUFCAccording to Laurie Whitwell, Ruben Amorim has extensively trialled a change of systems from his standard 3-4-2-1 to a 4-3-3 out of necessity. This is as a result of Mazraoui, Diallo, and Mbeumo being key players in the regular system, and the squad lacks direct profiles to replace them. Deployed mostly as a right-sided centre-back, Mazraoui was named in the Morocco squad for the AFCON, and will likely start at right-back for his country in the tournament. Diallo and Mbeumo were invited by reigning champions Ivory Coast and Cameroon, respectively, and will leave after the Bournemouth game.
