Manchester City v Sheffield United
Manchester City was on the right side of some contentious decisions as Sergio Aguero's controversial goal and a late Kevin De Bruyne effort earned a 2-0 win over Sheffield United.
With Premier League leader Liverpool having extended the gap at the top with a win over Wolves, City was fortunate not to fall behind in the first half when Lys Mousset had a goal harshly disallowed by VAR.
However, there was more controversy to follow, with the visitor incensed after referee Chris Kavanagh failed to stop the play despite accidentally blocking off John Fleck in the build-up to Sergio Aguero's opener.
