Celtic boss Ronny Deila has offered his apologies to 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. Celtic have signed Dundee United winger Gary Mackay-Steven on a pre-contract agreement Dundee United manager Jackie McNamara has hit out at Celtic's attempt to acquire Mackay-Steven 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. He (Deila) has his own way of doing things but I wouldn't want to speak about one of his players under contract.'
