Cristiano Ronaldo has hinted he will make his Manchester United return against Rayo Vallecano this weekend - saying 'Sunday, the king plays'.

Ronaldo was not included in United's 21-man squad for Saturday's friendly against Atletico Madrid in Oslo, with the forward still wanting to leave the club after talks this week.

But in a comment on Instagram he suggested he would feature in United's match against Rayo Vallecano on Sunday.

Ronaldo and his agent Jorge Mendes held meetings with United at Carrington on Tuesday, but his position remains unchanged and he wants to play for a club in the Champions League and win major trophies.

United do not want him to go, however, and Ronaldo has started training with the team having missed the club's pre-season tour of Thailand and Australia due to family reasons.

His potential options elsewhere are limited. Chelsea are not an option anymore, while Bayern Munich and Atletico appeared to publicly rule themselves out this week.

Atletico fans displayed a banner stating 'CR7 not welcome' at a pre-season friendly on Wednesday.

Although there are major issues to overcome for Ronaldo to join Atletico, Sky Sports News has been told by one source not to completely rule it out yet.
