This is why it’s the silly season.

In what might be the most shocking transfer this year, former New York City FC and United States national team midfielder Mix Diskerud somehow secured a move to Premier League giants Manchester City on a free transfer.

Diskerud agreed to a four-and-a-half year contract with the Premier League leaders. The move was oddly announced on Twitter by apparel company Umbro, who Diskerud has a partnership with.

The 27-year-old MLS flop will not train with Manchester City nor will he likely ever appear in a game for the club, a source said. The move is a low-risk, high-reward potentially for Manchester City, who could potentially benefit from a future transfer fee if Diskerud regains his lost form.

It’s not likely that Diskerud will loaned to a City Football Group owned-team. CFG owns both Manchester City and NYCFC among other clubs in the world.

NYCFC cut ties with the once-promising midfielder just before the start of last season when they bought out his contract. While he remained signed to MLS, Diskerud was loaned to Swedish side IFK Goteborg for the rest of the year.

Once one of NYCFC’s premier signings during its inaugural season in 2015, Diskerud showed promise under then-head coach Jason Kreis, appearing in 27 matches. He scored three goals, including the club’s historic first, in 2015.

But after Kreis was fired at the end of 2015, Diskerud quickly fell out of favor with Patrick Vieira, who relegated the former U.S. international to the bench. He appeared in just 12 matches before being cast off in 2016.

He’s made 35 appearances for the U.S. national team and was selected to the 2014 World Cup. His last appearance for the national team was in early 2016.

Diskerud’s contract with NYCFC and MLS was set to expire at the end of 2018, according to ESPN.

It remains unclear why Umbro decided to announce the signing.
