Hernandez, or ‘Chicarito’ as he’s more commonly known, has been in fine form in the Bundesliga for Bayer Leverkusen, scoring 11 goals in 15 appearances for the German side. His best game coming against Borussia Mönchengladbach where he took home the match ball following his show-stopping hat trick.
Hernandez joined United after the 2010 World Cup, with the transfer having been agreed before the tournament, but kept under wraps, with only Hernandez and his father being the only non-representatives aware of the deal.
In his five years in Manchester, Hernandez made 157 appearances and netted 59 times for the Mancunian side.
He spent last season on loan to Spanish giants Real Madrid, having fallen out of favour with new boss Louis Van Gaal. He scored nine times in 33 outings with Real.
Liverpool have previously been linked with Hernandez in the summer, and were believed to have gone as far as to bid for him, however, no transfer ever arose from the rumours.
