I think people are underestimating how big Under Armour are in America. They have two of the biggest stars in The NBA and NFL, Stephen Curry and Tom Brady. Stephen Curry is predicted to be the next Michael Jordan and it's estimated he could raise UA's worth to $28bn. They've grown 430% in the last 5 years which is spectacular. They're are a fantastic and innovative company to be associated with. They've over taken Adidas in North America sales and are just behind Nike now and are desperate to become a major global brand. Nothing would promote that more by sponsoring a Tottenham team in the Champions League (fingers crossed). Having family in America I came onto Under Armour not long after they started out, I'm a but of a fanboy as you might of guessed and have a vested in the company. You can imagine my face when they signed with Spurs, it was like watching my missus have it off with Emily Ratajkowski. They've been out bidding Nike on a lot of contracts recently, hopefully Spurs might be another one!
