Portuguese giants FC Porto complete the line-up for the pre-season Colonia Cup.

Stoke City had announced last week that they would be participating in the Colonia Cup which is set to be held in Cologne, Germany just a week ahead of the start of the upcoming Premier League season.

Along with Stoke, host FC Koln and Valencia were named as the participating teams.

Now to complete the line-up for the competition, it has been confirmed that Porto will be the fourth team to join the tournament.

"It will be an attractive weekend for the city of Cologne as the RheinEnergieStadion will host international powerhouses Valencia, Stoke City and Porto," said a statement on the Koln website today.
