Why Richarlison should think twice before joining Man United if they firm up their interest this summer

Watford forward Richarlison has been linked with a move to Chelsea since pretty much the moment he stepped off the plane from Rio eight months ago.

But it now appears that the Blues have competition, with the Daily Mirror reporting that "José Mourinho is ready to gazump his old club" in the race for his services.

It is easy to understand Manchester United's interest. He may have gone off the boil since that swaggering start to life at Watford, but most of the ingredients for superstardom are there: the pace, the two-footedness, the balance, the steely-eyed desire.

What is less clear is what he would stand to gain from a move to Old Trafford at this moment, as I argue in my latest Unibet piece.

Ronaldinho interview: On retirement, replacing Messi, Coutinho's Barcelona DNA and the beauty of the toe poke

"I can only thank God for the gift that he gave me, and for the opportunity to do the thing that I love the most.

"God put me on this earth to play football and I had a lot of fun with it."

That's Ronaldinho reflecting on his playing career to yours truly, in an interview conducted in Mexico City, of all places.

Read (and indeed watch) what he had to say about his decision to retire, the problem of replacing Lionel Messi, Philippe Coutinho's Barcelona DNA and plenty more on the Yahoo Sport website.
