Joint-Chairman David Sullivan is confident that the Hammers' hard work in the transfer market is about to bear fruit.

Having secured their place in the Barclays Premier League with a strong second half of the 2013/14 campaign, the Joint-Chairman's focus this summer is on building a squad capable of pushing up the league table and entertaining the Boleyn Ground crowd on a regular basis.

The Hammers have already captured the signature of striker Mauro Zarate, who top scored in the Argentine Primera Division last season, and have their eyes on a number of exciting new additions as they prepare for a third season back in the top flight.

Manager Sam Allardyce has been identifying players all over the world since the close of the campaign and Mr Sullivan revealed that the Club are close to capturing one of their prime targets.

He said: "We've been working extremely hard to bring in the players we know we need to improve the squad ever since the end of the season, and I believe we are very close to putting the finishing touches on a transfer that will excite us all.

"Should we land this player, we would have had to beat off competition from some of Europe's top sides, and for me that shows the direction we are taking as a Club right now.

"We all know we need to improve from what we achieved last year, and this summer's recruitment is going to be key to that. We have already made what I am sure is going to prove to be an outstanding signing to increase our firepower up front, and we will make several more across the board as the summer goes on."

One of the biggest plus points from the 2013/14 campaign was the Hammers' resilience at the back as they secured 14 clean sheets. However, goals were in shorter demand than desired at the other end and the Joint-Chairman has already set about addressing that issue.

The Club have secured the services of Teddy Sheringham as attacking coach as they go about the aim of scoring more goals this season and Mr Sullivan is clear on the type of player he, and Allardyce, are targeting.

He added: "We want to see players who can play in any of the three attacking positions and score goals and who have a proven record of scoring goals.

"We want people who take on players and go past them, people who can shoot from the edge of the penalty box, people with movement, because there is not enough movement and speed in our team.

"We hope, by bringing in slightly younger players, we will also get a bit more from the players we've got, because they know their name is not automatically going to appear on that teamsheet every match - there is going to be somebody pushing hard for every single place.

"We're going to have two players in every position competing for that place in the team. We do need players with a proven track record and that's what we'll be trying to do."
