Portuguese champions Porto became the last club to confirm its presence at the traditional pre-season Guadiana Tournament.

The three-way competition at the Stadium of the Algarve on July 26, 27 and 28 will also feature Newcastle and top Greek side Olympiakos. Benfica, who are normally regular visitors to the Algarve, are absent this year due to a clash of dates with their own Eusebio Cup.
