No player did more to stop the flow of American talent to Europe than Jozy. The Daily Mail published a list of the worst strikers in EPL history a few years ago. Jozy came in at #1 and it is hard to dispute their reasoning.
Jozy Altidore played 70 Premier League games for Hull and Sunderland. He scored a grand total of two Premier League goals. After a fairly non-eventful loan spell with Hull in 2009-10, he returned to England in 2013 after a prolific few years in the Dutch league with AZ. Sunderland, managed by Paulo Di Canio, spent £6m on the US international and he repaid their faith with one strike in 42 league games. Altidore looked big and strong, like anything could hit him and stick. He should have been a colossus, but he just wasn't. Clumsy on the ball and wild in front of goal it was the worst of combinations to spearhead a struggling Sunderland side battling relegation. He left for Toronto in January 2015, with a strike rate of one goal every 35 games that few Premier League strikers can hope to rival.
He was also awful in the World Cup with 0 goals in 5 games. He also scored a grand total of 1 goal against Mexico (in a friendly for his first international goal). He's a flat track bully who made his living dominating overmatched competition while bottling the biggest moments/opportunities of his career.
