It was a signing out of the blue really. United missed out on Pedro and Martial is not a household name in this country; he was an up-and-coming player in France. He played against Arsenal last season in the Champions League but it's certainly not a name that resonates in the Premier League, so it was a big shock. The price that was paid obviously raised eyebrows but, like with any transfer fee, if any player succeeds and does well he is worth it.
