Wait no more, Wayne Rooney.Mauricio Pochettino is probably too busy at the moment to return your calls, but a quick internet search has answered the former Manchester United and England forward’s burning question about the U.S. men’s national team coach’s signature navy overshirt and matching pants: it’s Hugo Boss.Rooney is hardly the only one who has taken notice of the Argentine’s touchline wardrobe. The navy lightweight wool overshirt with matching wide-leg trousers, crisp white T-shirt and white Nike sneakers are quickly becoming part of the USMNT coach’s World Cup identity. The look, according to a U.S. soccer spokesperson, is entirely Pochettino’s own choice. Hugo Boss told The Athletic in an email that they had made two dedicated versions of the navy lightweight virgin-wool ensemble, customized with the USSF badge, for Pochettino for the tournament. Fortunately for everyone involved, the outfit is washable. If the U.S. keeps winning, Pochettino does not have to choose between hygiene and good luck. U.S. Soccer staff can simply keep his matchday look fresh and clean. The 54-year-old has worn the same outfit for both of the USMNT’s group-stage victories, the 4-1 rout of Paraguay in the opener and the 2-0 win over Australia that secured a place in the Round of 32 with a match to spare.

If the U.S. keeps winning and gets past Turkey on Thursday, Pochettino’s new signature ensemble may soon take on a life of its own.
