Garnacho, who returned early to Manchester United after the Copa America, has opted to put in some extra hard work following his miss, according to the Daily Mail. The Argentina international has been working at the NAS Elite Sports Performance Centre in a bid to get himself into prime shape and burn off some frustration. The facility is a favourite of Premier League stars and gives players access to a range of services including physiotherapy, IV Drip Therapy, nutritional support and many other wellness treatments.
