See the new signings at the Boleyn Ground for the first time when we take on Italian giants UC Sampdoria for the Marathonbet Cup.
It has been a busy summer in the transfer market for the Hammers, with defenders Aaron Cresswell and Carl Jenkinson, midfielders DIego Poyet, Cheikhou Kouyate and forwards Mauro Zarate and Enner Valencia all signing up.
Cresswell, Poyet, Kouyate and Zarate could all play a part and you could be there with prices on the day at £15 for U16s and £25 for Adults. The Stadium Ticket Office opens at 9am, with cash turnstiles also available from 1.30pm until kick-off.
A Family Fun Zone will be open in the Alpari Stand Car Park from 1.30pm, where the kids can test their skills in a penalty shootout or have a kickabout on our mini inflatable pitch.
Managed by former Yugoslavia defender Siniša Mihajlović, Sampdoria finished 12th in Serie A last season but will be hopeful of challenging for a European place next term.
The Genoa-based club possesses a cosmopolitan squad featuring the likes of Italy striker Manolo Gabbiadini, Serbia midfielder Nenad Krsticic, Iceland midfielder Birkir Bjarnason and Poland duo Bartosz Salamon and Paweł Wszołek, while Mihajlović's team is captained by Daniele Gastaldello.
Two Sampdoria players have experience of English football - Germany international defender Shkodran Mustafi spent two years with Everton as a youngster, while Italian forward Stefano Okaka scored Fulham's winner in a 3-2 Premier League victory against West Ham at Craven Cottage in May 2010.
West Ham have met il Doria just once previously, but Hammers fans will be hoping for better than the 6-1 Makita International Tournament defeat suffered at Highbury in August 1991. That day, Renato Buso scored four times and Toninho Cerezo and Attilio Lombardo once each for the Italians, with George Parris netting the Hammers' consolation goal.
In all, Sampdoria won the Makita Tournament in three straight seasons between 1990 and 1992, beating Arsenal in two finals before overcoming Leeds United in the third.
The Italian club will be visiting England for the first time in seven years, with Alan Smith scoring Newcastle United's winner in a 1-0 victory at St James' Park in August 2007 during their last visit to the country.
The visit of Sampdoria completes a rich and varied pre-season schedule for Sam Allardyce's squad, which includes fixtures against seven teams from six different countries.
