deila sorry for his loose talk

Celtic boss Ronny Deila has offered his apologies to his Dundee United counterpart Jackie McNamara who has criticised his conduct in the Gary Mackay-Steven deal.

The 24-year-old Tannadice winger last week signed a pre-contract agreement which will see him join the Hoops in the summer. To McNamara's ire, Deila spoke publicly of taking him during the transfer window, although the reported fee of £250,000 is a stumbling block.

The former Parkhead defender said: "I like to speak about players behind the scenes and I don't think it's right to speak publicly about it."

Ahead of the visit of Motherwell tomorrow, where Celtic will leapfrog Aberdeen to the top of the table with a win, the Norwegian was surprised by McNamara's complaint.

"I just have to say sorry if that offended him in any way," he said. "This is a rule that I haven't heard before so I have to learn from this."
