David O'Leary is threatening to trump Celtic for Bolton Wanderers defender Danny Shittu.
Shittu was released from his Bolton contract last week and spent the weekend mulling over an offer from Celtic.
However, the Daily Star Sunday says Shittu is set to snub Celtic to join-up with O'Leary in Dubai.
O'Leary, with Celtic hero Roy Aitken his No2, is in charge of the ambitious Al Ahli.
