Victor Valdes appears to have directed a cryptic message at Manchester United manager Louis van Gaal by claiming that he will "fight to be free".

The Spaniard had a reported bust-up with his Dutch manager, resulting in the goalkeeper being shunned from the first team.

It is believed that Valdes, who joined United on a free contract in the summer, a year after leaving Barcelona, has been trying to orchestrate a transfer, but so far, no deal has been struck.

On Twitter, Valdes posted a picture of his hand holding a message, which read: "What doesn't kill you makes you stronger."

Alongside the photo, the 33-year-old tweeted: "To not let down those that want to see me play again is my motivation. I fight to be free and to enjoy my profession."

No defraudar a los que desean volver a verme jugar, mi motivación.
Lucho por ser Libre y disfrutar de mi profesión. pic.twitter.com/rhs7tCNofo
