It is said that Manchester United was pursuing Ronald Araujo but gave up on this transfer recently.

The Red Devils has been in intense search of defenders these days. This is the best thing for them as it has been their weakest point. However I assume there isn't much progress on a player so far. I didn't even know they were interested in Araujo. But it is good to hear they have dropped their interest. 

I mean he really tends to make simple mistakes. We have seen many examples at Barcelona. I don't believe he is reliable.
