The West Ham fans down in the Transfer Tavern believe this might be the best Premier League side they’ve ever brought to Old Trafford as the sides prepare for Sunday’s clash.

West Ham were slow starters in the transfer window, but have excited their fans with a recent double swoop for Marko Arnautovic and Javier Hernandez.

£25m Arnautovic was Stoke City’s MVP last season, while Chicharito was equally impressive for Bayer Leverkusen. The Mexican will be keen to show his former side how much he has progressed since his departure in 2014.

As for Mourinho’s side, it’s an opportunity for United to swiftly move on from their 2-1 UEFA Super Cup defeat to Real Madrid.

Mourinho will be desperate for a quick start and an early goal to keep the Old Trafford faithful in good spirits.

Take a look at the TWO things that will decide Man Utd vs West Ham on Sunday…

ROMELU LUKAKU’S DEBUT

The Belgian has a superb record against the Hammers. He’s scored seven times and assisted four in 10 Premier League outings.

Slaven Bilic will be wary of Lukaku’s threat and needs his centre-backs to have a fine game in order to keep him quiet.

JAVIER HERNANDEZ’S RETURN

It may just turn out to be a day decided by clinical finishing. Javier Hernandez over the years has established himself as a fox in the box.

West Ham will be relying on him to snuff out a goal or two, though David De Gea will take some beating.
