Talking Tactics: Arsenal formation fix; Chelsea stale; Liverpool miss fullbacks;

Arsenal's well deserved victory over Chelsea at the Emirates on Saturday could prove to be a huge result and performance for three Premier League sides. The hosts appear to have finally found the right formation to maximise their talents, Chelsea reached breaking point with Maurizio Sarri laying into his players after the match, and Manchester United moved within three points of the top four.

There weren't too many other stories developing over the weekend, although a couple of 4-3s livened up Match of the Day on a Saturday in which, across eight games, only one point was won by the away teams.
