Manchester City are set to boost their power in the transfer market with the capture of top Nike exec Garry Cook.

The Daily Mail says Cook is being offered the position of executive chairman by Thaksin Shinawatra and his appointment will strengthen their hand in negotiations for the world's top players.

Ronaldinho, for instance, has been in talks with City's current board through his brother and agent, who recently visited the club. The Brazilian is one of Nike's leading football ambassadors.
