It seems that word of Koke's departure from Aris and reported signing with the Houston Dynamo is spreading across Europe. Two Spanish sources are corroborating the story, though it should be noted that the Spanish media is sometimes less than reliable.

For those of you who were wondering, Koke can play either as a forward, center-attacking midfielder, or, if needed, on the wing, all areas the Dynamo could use reinforcements.
