My feeling is that Al-Qadsiah will not be satisfied with just signing Nacho and they will likely add new ammunition to the striker and midfielder positions.
They already have big names in those positions, for striker they have Luciano Vietto & for midfielder they have Andre Carillo, but because they're a promoted team that will play in the SPL in the next season, I'm sure they will bring in other top players, no in the midfielder or striker position, maybe it's a goalkeeper or another defender (especially CB). However, so far I don't have any new information regarding the Al Qadsiah transfer rumors and which players might go to this team.
