Nigel Worthington has expressed his frustration after trying - and failing - to speak to Newcastle's Shane Ferguson about a call-up to the Northern Ireland squad.

Worthington attempted to contact the defender ahead of Friday's Euro 2012 qualifier against Estonia. The issue is complicated by suggestions earlier this year that Ferguson was considering switching his allegiance to the Republic of Ireland, but he has since returned to play for Northern Ireland Under-21s.

Worthington said: "I've been trying for the last 36-48 hours to get in contact with the boy to let him know I'd like to draft him into the squad. The club has been notified and we've had the medical records sent back to us, as we always do with players to see if there are any problems, but we've had no contact."
