The Manchester United fans here in the Transfer Tavern believe they are genuine contenders for the Premier League this season following their thrashing of West Ham.

Jose Mourinho’s side dispatched the Hammers 4-0 at Old Trafford on Sunday to set the tone for the 2017/18 campaign.

It appears Mourinho may have solved his goalscoring problem after Romelu Lukaku netted twice on his league debut.

Anthony Martial stepped off the bench to make it three before Paul Pogba scored a fourth late on.

The Red Devils tallied just 26 Old Trafford goals last term, two less than relegated Hull City.

It’s a great start for United, but it is just one game – and West Ham were poor.

Slaven Bilic would have been furious with Arthur Masuaku’s laughable attempt to defend for Lukaku’s opener, while Javier Hernandez received little support going forward.

Take a look at THREE things we learned from United’s 4-0 win…

WEST HAM’S SHODDY DEFENCE

It should be noted, the Hammers were terrible in defence and largely ineffective going the other way.

Slaven Bilic has a lot of work to do before the transfer window slams shut.

The only positive from the game was Javier Hernandez’s performance.

The Mexican impressed as he tried his hardest to get the West Ham machine going.

MATIC THE PROBLEM SOLVER

If the first game of the season is anything to go by, the Serb is already looking like one of the signings of the summer.

Matic controlled the game from start to finish, was dominant in the air and on the ground, simultaneously allowing Paul Pogba the freedom to get forward.
