West Ham United owner David Sullivan certainly isn't the most popular figure among the London Stadium faithful after what has happened in recent years, but if he follows up the appointment of Manuel Pellegrini as the club's new manager with some exciting new additions this summer, that situation could quickly change.

The 69-year-old took action and decided that David Moyes shouldn't stay on with the east London outfit following the expiry of his contract at the end of the season, and he certainly delivered what the fans wanted in that instance.

Sullivan certainly hasn't got many things right during his time at the helm, but appointing a previous Premier League title winner, whom Hammers supporters on Twitter are keen to see link up with £140,000-a-week attacker, and giving him control of who the club recruits is certainly a big step in the right direction.

While the Irons are looking pretty good from an attacking point of view –Pellegrini will hope to convince Javier Hernandez and Manuel Lanzini to stay – more work is needed in midfield and at the back given they had the joint-worst defensive record in the top flight this season.

Here are three signings Sullivan must deliver for Pellegrini this summer to ensure he goes from zero to hero among West Ham supporters…

According to reports in The Sun, West Bromwich Albion centre-back Ahmed Hegazi is available for just £2.5m this summer because of a clause in his contract after the Baggies were relegated from the Premier League, and West Ham should be looking to snap the Egypt international up for that bargain price.

The Irons struggled from a defensive point of view this season and need reinforcements in that area following the departures of Jose Fonte and James Collins in the last few months, and the 27-year-old certainly fits the bill.

First and foremost he has shown with the Baggies that he is a good defender who isn't afraid to put his body on the line for his team, while he is also strong and decent in the air and now has a year's experience at this level under his belt.

West Ham have long been linked with a move for the Sporting Lisbon midfielder and seemingly came close to getting him last summer, but it is a deal Sullivan must do this time around.

Cheikhou Kouyate and Mark Noble consistently produced below-par performances in the middle of the park for the Irons this season, and it is clear to see that the east London outfit are missing some strength and power in the middle of the park – something Carvalho would deliver.

The Euro 2016 winner would also provide a much-needed barrier in front of a leaky backline, and allow Pellegrini to set up with a more attacking style next term.

Given he is 35 years of age the potential of addition of the Manchester City legend would likely split West Ham fans, but Sullivan should look to bring him to the London Stadium on a one-year contract.

The Ivory Coast international has shown the quality he has throughout his time in the Premier League, and while he may be getting on a bit and not quite have the athleticism he once did, he is hugely experienced and influential and will have a point to prove that he should still be a regular starter at this level.

The fact that Pellegrini already knows him well and knows what it takes to get the best out of him is just another reason why he must be in an Irons shirt next season.
