"Gareth is fine. He is still a Real player with three years left on his contract. He has always been clear about that. And if he is picked he will play. You would have to ask Mr. Zidane what he wants to do. But Gareth will keep trying."
Manager Zinedine Zidane offered a response when asked why he had left Bale out of Sunday's trip to Anoeta:
Bale has had a tough season at Real Madrid and has made just 21 La Liga starts for Los Blancos, racking up eight goals and three assists.
The forward has struggled for form and fitness throughout the campaign, and Zidane's decision to drop him suggests his time at the club is coming to an end.
Yet finding a buyer for Bale may be difficult because of his age, injury record and the finances that will be needed to complete a move.
Barnett told Sky Sports News that a return to the Premier League was not out of the question but warned that Bale would be an expensive signing.
"It certainly is possible, if somebody puts their hand in their pocket and pays us what we think he deserves. It is going to be a lot of money!"
Ligue 1 champions Paris Saint-Germain have also been linked with the Welshman. The French side are willing to spend £180 million on Bale, Isco and Toni Kroos, according to Le Parisien (h/t Joe Strange for MailOnline).
Barnett's comments suggest Bale is determined to stay at Real Madrid, but Zidane seems to have made it clear that the Welshman is no longer in his plans at the Santiago Bernabeu.
