​McGregor has been linked with a move to Saudi Arabia in recent months, while comments he made in April about matching his ambitions led to suggestions he could consider leaving Celtic.AdvertisementAdvertisementAdvertisementO’Neill, however, believes those remarks have been taken out of context and insists the midfielder has given him no indication that he wants to move on.The Celtic boss told Daily Record “Sometimes those things get lost in translation a little bit.“I don’t think he meant it as bad as that. I know I used to do that myself as a player – ‘Had the club matched my ambition?’, and then I found out I wasn’t in the team. That’s what Brian Clough used to do.“I haven’t had a conversation with him. I will do during the course of pre-season, see how he’s fixed. He was terrific for us, absolutely terrific.“He’s been a really good captain anyway, but last season, right from the start, from the first time that I came in in late October, until right to the end of the season with the second spell, I thought he was brilliant.AdvertisementAdvertisementAdvertisement“He is really important to us in many aspects because he knows the football club.

He hasn’t brought it up at this moment, so maybe if he doesn’t speak to me, it’ll be all right.“But if he does, I will tell him that we want him at the football club. But obviously if something comes in that is just mind-boggling for him, that becomes a different issue.”Elsewhere, O’Neill discussed changes to his backroom team following Gavin Strachan’s departure to West Bromwich Albion, with Ross Grant arriving from Hearts as Celtic’s first dedicated set-piece coach.AdvertisementAdvertisementAdvertisementGrant earned plaudits after helping Hearts become one of the Premiership’s strongest teams from dead-ball situations last season, and O’Neill believes his appointment reflects the growing importance of specialist coaching.The Irishman said: “I don’t know whether we headhunted him. I think his contract was up. Mark Fotheringham knows him and I think when it became available, I wanted to do it.“And wi
