Georginio Wijnaldum's 70th-minute goal settled the affair to ensure the Reds' lead at the top of the Premier League will be at least five points at the end of the weekend.

Sixteen and counting
Liverpool extended their Premier League winning streak to 16, but had to work extremely hard for the three points in Sheffield.
It means the run now stands just two short of the record set by Manchester City in 2017.
The Reds were given a fair number of scares by Chris Wilder's side and Wijnaldum's goal was the visitors' first shot on target in the match.
