New Balance says it will "vigorously defend itself" after a report said Manchester United's Marouane Fellaini is suing the company because its boots injured his feet.

As reported by The Sun, Fellaini filed litigation at London's High Court, claiming the New Balance boots he wore as part of an endorsement deal caused him "loss of enjoyment, inconvenience and impact on performance" and asking for £2.1 million.

Fellaini, who signed the endorsement deal while playing for Everton, said the boots needed to be "steamed and stretched" by equipment managers before he could wear them, and that he made repeated complaints to the company.
