According to site topdrawersoccer.com, Villarreal have signed USMNT young player Mukwelle Akale from Minnesota Thunder Academy. Akale played the Copa del Atlántico earlier this year with the US U-18 team. The US failed to win any of the single matches they played, but nonetheless, Akale was choosen as the tournament best player.
I presume Villarreal scouted Villarreal while he was playing the tournament obviously. According to the site he is set to travel on monday to sign his contract with the 'Yellow Submarine'. It'l be interesting how he develops. So far it seems Villarreal has a diamond on the rough. The reviews on Akale are generally positive.
Here's a video by the USMNT on Akale :https://www.youtube.com/watch?v=CjF4aSSYZl4
