West Ham United are happy to confirm that the Club will take part in the Torneio do Guadiana in Portugal.
The three-team pre-season competition will be held at the Estádio Municipal de Portimão in the Algarve, with the Hammers taking on Sporting Clube de Portugal and SC Braga.
The Hammers will take on Sporting Clube de Portugal on Monday 5 August and SC Braga on Tuesday 6 August, with both matches kicking-off at 9.15pm local time.
Sporting will take on Braga on Wednesday 7 August, with the winners of the competition following in the footsteps of previous winners Sporting, Real Betis Balompie, SL Benfica and Newcastle United.
"We are honoured to be involved in such a prestigious pre-season tournament against two of Portugal's best sides in Sporting Clube de Portugal and SC Braga," said manager Sam Allardyce. "The Guadiana Tournament will be the perfect preparation for our 2013/14 season in the Barclays Premier League and both myself and my players are very much looking forward to taking part in it.
"Sporting Lisbon are one of Portugal's oldest and most historic clubs, having won the Portuguese title 18 times and the European Cup Winners' Cup in 1964 - a year before us!
"We played Braga in a pre-season match in Portugal a year ago and it was a very competitive match which ended in a 1-1 draw. Braga are a club with a proud recent history, having reached the UEFA Europa League final as recently as 2011, and we look forward to facing them again.
"The weather and facilities are sure to be superb and we are all relishing the opportunity of getting down to work on the Algarve, a region of Portugal where many West Ham fans either make their homes or regularly visit for holidays."
Sporting finished seventh in the Primeira Liga last season. Managed by Leonardo Jardim, the club from the capital will be hoping to bounce back this term. Among the star names in Jardim's squad are Portugal goalkeeper Rui Patricio, Argentina defender Marcos Rojo, Spain winger Diego Capel and Peru forward Andre Carrillo.
Braga will face the Hammers for the second pre-season in succession, having held Sam Allardyce's side to a 1-1 draw at the Estadio AXA in August 2012, when Winston Reid scored a late equaliser.
The Archbishops have been busy in the transfer window this summer, bringing in goalkeepers Cassio and Eduardo from Pacos de Ferreira and Genoa respectively, Serbian full-back Aleksandar Miljkovic from Partizan, defenders Vitor Bastos and Joãozinho from Vitória Guimarães and Beira-Mar and strikers Edinho and Salvador Agra from Malaga and Real Betis respectively.
West Ham supporters can watch the match from the East Stand, with tickets costing just €12.50 each. Hammers fans can buy their tickets in person from the Ticket Office at the Estádio Municipal de Portimão on matchdays. Alternatively, you can buy tickets online here.
The 9,544-capacity stadium is home to Portimonense Sporting Clube, who finished sixth in the Portuguese Segunda Liga in 2012/13.
