Dundee United boss Jackie McNamara has confirmed that a bid has been received for Ryan Gauld, adding that the opportunity could be "life-changing" for the player.

McNamara refused to reveal which club had submitted the bid for the 18-year-old but STV understands the offer has been made by Sporting Lisbon, with the figure standing at £2.2 million plus add ons.

Gauld travelled to Lisbon on Tuesday morning to discuss the transfer, but is due back in Scotland on Wednesday for training.

Speaking at pre-season training McNamara said: "Yes, we have had a bid for Ryan and he's been given permission to speak to a club but that’s as far as it’s gone at the moment.

"There’s still a lot of issues to be resolved on both sides, with the bid and on Ryan’s side of things. That’s as much as I can tell you at the moment. There are a lot of things to be ironed out."

The Tannadice boss admitted that if Gauld does decide to make the move to Portugal he will be sad to see the teenager leave the Tayside club.

"I wan’t to keep them all," said McNamara. "It’s the same with Andrew Robertson and John Souttar, Stuart Armstrong and [Gary] Mackay-Steven.

"It’s something that I’ve had to deal with since I came here, with Johnny Russell leaving, and it’s something that will continue. It’s obviously a healthy thing for the club to have talent that everyone wants to take off you.

"But personally and perhaps selfishly I want to keep hold of them for as long as I can. But there comes a time when it’s too good to turn down, not just financially but for the player himself. If it’s the right club it could be life changing.

"The initial offer was good enough for us to let Ryan go and speak to them. We’ll just need to see what happens over the next 24 hours."
