Chelsea and Manchester United played out a dour goalless Premier League draw at Stamford Bridge. Both sides largely cancelled each other out, and neither side perhaps deserved all three points.Manchester United felt they had a penalty claim denied early in the first half after a Marcus Rashford free-kick was saved by Edouard Mendy and seemingly hit Callum Hudson-Odoi's hand inside the box. However, following a VAR review, no penalty was awarded.Despite the controversial call, the tempo of the game remained high, with both teams matching each other for most of the game.Chelsea got their best chance soon after the restart when Ben Chilwell's cross found Hakim Ziyech in the box. However, an alert David De Gea produced a fine save, and Luke Shaw blocked Reece James' ensuing follow-up effort.In the 63rd minute, it was the turn of the Chelsea custodian to make a save; he did so by blocking Scott McTominay's shot with his chest. Both sides pressed for the winner, but was a winner was not to be.The spoils are shared at Stamford Bridge.🔴 #MUFC#️⃣ #CHEMUN🏆 #PL@Chevrolet— Manchester United (@ManUtd) February 28, 2021Manchester City are now 12 points clear of Manchester United at the top, with Chelsea a further four points adrift.
