The 21-year-old, who has played primarily at full-back for the Reds but sees a central berth as his long-term future, responded with a display of confident authority.
Not only was Mane prolific in the attacking third, he also laid on two key passes, won three out of three tackles and made an intelligent inside run to create space for Robertson's opening assist. In some respects, that might be an odd benefit for him, because every goal and victory will now be a single raised middle finger to any opposition fan who bafflingly decides to direct their derision his way, potentially making them even more satisfying.

Just how Clyne feels about that is one to keep an eye on. They can, and probably will, get better. Another mid-table finish is probably the ceiling West Ham can expect this season, but a Europa League qualifying spot could be possible if they get on a hot start.
Despite getting off to a winning start against Leicester on Friday, all is still not well at Manchester United between star midfielder Paul Pogba, manager Jose Mourinho and executive vice-chairman Ed Woodward.
There was certainly a vast difference of the quality in midfield as Liverpool's high press coupled with their tendency to recover the possession in advanced positions troubled the West Ham players.
