Ahli coach Manuel Jose said there were no secrets to hide before taking on Ittihad Jeddah in the World Club Championship on Sunday.

"All strengthens and weaknesses of both teams are well known and I wish Ahli and Ittihad give a good example of Arab soccer," Jose told a press conference on Saturday.

Ahli will play Ittihad in their opening match in Japan and the winners will clash with Brazilian side Sao Paolo in the semis.

The Portuguese coach said his players are pretty focused and enjoy high spirits but he voiced concerns over what he called the "kick-off nerve" that may hit some players in the beginning of the game.

Asked about his players' adjustment to the low temperature, Jose said it is not too cold in Japan for Ahli, adding that cold weather forces players to exert more effort to get warmed.
