Manchester City provided the perfect response to Liverpool’s climb back to the top of the Premier League table as they destroyed Chelsea 6-0 to reclaim first place.

Here are six things we learned from the Premier League this weekend

Sergio Aguero is only human after all

Sergio Aguero hammered a record-equalling 11th top-flight hat-trick as Manchester City hit sorry Chelsea for six. However, while the expert finisher demonstrated his prowess once again, he was guilty of a glaring eighth-minute miss when he side-footed wide with the goal at his mercy after Bernardo Silva had served up the ball on a plate.

Wijnaldum an unsung hero for Liverpool

Often overshadowed by the firepower of Liverpool’s front three and the defensive stability brought by the signings of Virgil van Dijk and Alisson Becker, Georginio Wijnaldum has quietly tightened Liverpool’s midfield all season. The Dutch midfielder was badly missed in a 1-1 draw at West Ham that saw Jurgen Klopp’s men hand City the chance to take top spot in midweek. Wijnaldum returned in style over the weekend, scoring with a delicate lobbed finish in Saturday’s 3-0 win over Bournemouth.

The goal capped an outstanding all-round display from Wijnaldum which only served to highlight the importance of keeping him fit for the title run-in.

Formidable Pogba fuels United charge

Paul Pogba’s demeanour during the dying days of Jose Mourinho’s reign as Manchester United manager was that of a man who had lost his way. Under Ole Gunnar Solskjaer, he has rediscovered the confidence, swagger and thrust which prompted United to invest £89.3million in his services and his adept finish from a tight angle and nerveless penalty, as well as his overall display, in Saturday’s routine 3-0 win at Fulham underlined his rejuvenation and that of Man United.

Lack of clean sheets could cost Arsenal

Arsenal beat bottom side Huddersfield 2-1 on Saturday to stay in position for Champions League places with Chelsea and a resurgent Manchester United.

Their failure to record their first away clean sheet in the league under Unai Emery after a late own goal did not worry the Spaniard unduly but their defensive vulnerabilities could ultimately prove decisive in the race for the top four.

Emery played down the issue, saying: “The clean sheet is important but our goal is to win. Maybe we can take a clean sheet and only draw.

Top flight survival still have a lot of drama

The battle for top-flight survival has taken a series of twists in recent weeks and there were more significant moves on Saturday. Wins for Cardiff and Burnley have dragged Crystal Palace and Brighton back into a pack also including Newcastle and Southampton three points separating the six clubs – with bottom two Fulham and Huddersfield in danger of being cut adrift.

Sarri needs to find a solution fast for his flailing Chelsea side

Chelsea were pummeled 6-0 by Man City over the weekend after losing 4-0 to Bournemouth a fortnight ago. These results shows there is trouble in Chelsea and Sarri needs to find a quick solution to this malaise. Maybe a revert of formation, or N’golo Kante played in his preferred position might just do the trick, but be that as it may, Sarri needs to come up with a change.
