Rhys Williams had a difficult game against Manchester United but the fact he played at all implies a flaw in the Anfield system
Three minutes into the second half at Old Trafford something happened that was simultaneously startling, avoidable, unfortunate, and also crushingly inevitable. Manchester United’s second goal in this fun, highly watchable 3-2 FA Cup fourth-round win will be cast as a the fruit of a Rhys Williams mistake.
Correctly so: it was a horrible mistake. Rumbling back to cut out a diagonal pass from Mason Greenwood, Liverpool’s centre‑back scuffed a miskicked clearance that ran straight into Marcus Rashford’s path, leaving him a clear run on goal.
