West Ham United will take on Spanish Primera Division side RCD Espanyol during the international break.
The Hammers will travel to Barcelona to take on Los Periquitos at the 40,500-capacity Estadi Cornellà-El Prat on Thursday 5 September, with kick-off at 9pm local time (8pm UK time).
West Ham will take a squad containing first-team players who have not been called-up for international duty to Spain, with the aim of retaining match fitness and sharpness ahead of the return of Barclays Premier League football at Southampton on Sunday 15 September.
Assistant manager Neil McDonald explained the thinking behind the trip.
"We just want to keep the lads ticking over and sometimes a game is very good in doing that," said McDonald. "The opposition that we're playing have a new stadium which sounds absolutely fantastic, so I'm sure the boys will have a really good run out and it's better than a training session."
West Ham supporters can attend the game, with tickets available for Sector 125 on the First Tier in the Away Team Supporters Corner. Tickets will be available through Espanyol's official website.
Managed by former Mexico international and boss Javier Aguirre, Espanyol finished 13th in the Primera Division last season and have started 2013/14 in fine form, drawing 2-2 at Celta Vigo before beating Valencia 3-1 at home on Saturday.
The club's best-known players are Portugal internationals Simao Sabrosa and Pizzi and Spain forward Sergio Garcia, while France U21 international Thevy Bifouma and Uruguay forward Christian Stuani have both made goalscoring starts to the new campaign.
