Disgruntled football fans have tweeted their comments at @moyesy, @rvp and @avb without realising that the users in questions have no relation to the sportsmen.
Sarah Moyes, who is a Scottish marketing worker, has suffered abuse online as fans sometimes mistake her for the United manager's daughter.
Indian technology expert Ravi Visvesvara Prasad has received messages aimed at Van Persie, while New York-based Ashley van Buren has had comments sent her way intended for Villas-Boas.
@avb yeah I heard, I'm very much looking forward to it blowing over! x— Sarah Moyes (@moyesy) March 27, 2014
