Bruno Fernandes fueled speculation surrounding a potential move to the Saudi Pro League after he was spotted dining with an Al Hilal star.
On the table is an offer believed to be worth £200milion over a three-year contract. Al-Hilal will push the Man United captain for a response to their £700,000-a-week tax-free deal, before approaching the Red Devils with an offer in the region of £100m.
Mail Sport understands Fernandes' agent, Miguel Pinho, spent three days at the Four Seasons hotel in Riyadh last week, where he held face-to-face talks with Al-Hilal officials.
But Fernandes' agent was not the only one in contact with Al Hilal personnel.
The player was spotted at Joao Cancelo's birthday party over the weekend, sharing a group meal to celebrate the former Man City star turning 31.
The two countrymen both suit up for the Portuguese national team, but the timing of this link-up will only send speculation soaring.
Fernandes just recently jetted back from United's miserable post-season tour in the Far East, where they limply lost in Malaysia against ASEAN All-Stars, in front of fans who had paid up to £260 to attend.
After the second game of their tour, in which they came back from a goal down to beat Hong Kong 3-1, Ruben Amorim insisted he does not believe Fernandes has played his last match for United.
The beleaguered boss: 'I don't think so. I don't know for sure. I think he wants to stay. He is saying no to a lot of things.
'The club can find other ways to make money. The feeling I get is that he wants to continue for sure with Man United, you never know.'
Fernandes' recent social media activity could also be seen as a hint that he plans on staying.
The 30-year-old reposted United's post on Instagram officially announcing Matheus Cunha's £62.5m move to Old Trafford on Sunday.
United sources have re-iterated that they do not want to sell Fernandes, but the club are under even greater financial pressure after their defeat by Tottenham in the Europa League final cost them £100m in Champions League revenue.
Speaking after the final, Fernandes himself acknowledged the possibility of a summer exit.
He said defeatedly: 'If the club thinks it's time to part ways because they want to do some cashing in or whatever, it's what it is. Football sometimes is like this.'
Al Hilal are keen to sign the Portugal international in time for the revamped 32-team Club World Cup, which begins on June 14.
They have been drawn in Group H alongside European champions Real Madrid, Red Bull Salzburg and Mexican side Pachuca.
