Marc Cucurella’s second-half header secured a vital 1-0 victory for Chelsea over Manchester United at Stamford Bridge on Friday.
The win lifts Chelsea to fourth in the Premier League, level on points with Newcastle and Aston Villa in the race for Champions League qualification.
A Maguire goal was disallowed for offside in the first half, and a Chelsea penalty was overturned by VAR after the break.
However, Cucurella struck in the 71st minute, heading in a James cross. Madueke missed a chance to extend Chelsea’s lead.
The defeat marks Manchester United’s 18th league loss this season, leaving them in 16th place and winless in eight matches.
Chelsea now look ahead to their final league game against Nottingham Forest and their Europa Conference League final.
United prepare for their Europa League final before facing Aston Villa in their last league fixture.
