Manchester United shot-stopper David De Gea has posted a heartfelt tribute to his countryman and former teammate Juan Mata.

The latter departed United this summer after the expiry of his contract, ending an eight year association with the club.

Mata has been at United since 2014, and grew close to De Gea during this years.

"Thought this would be a very difficult one to express into words but when I thought about it more, the main feeling I am left with is happiness," De Gea wrote in a lengthy Instagram post.

"This guy has been a teammate, a friend and is my family. The ultimate professional, one of the best players and people you could have grace your life. I'm so thankful to have been on so many journeys with you, happy that our paths crossed, and we shared a dressing room together.

"I love you my brother, I wish you everything and absolutely nothing but joy and success in your next stage of an unbelievable career."
