Don't believe Zubi will leave. And they could possibly use some of that Le Normand money to renew Merino.
Despite selling RLN I think they are quite solid covered at CB but will probably still bring someone. Might try to get Inigo back (not sure fans would like that though).
But I do believe they need to sign a better striker. Really a mistake on their part they didn't buy Sorloth and let him go to Villarreal. Sadiq is just not the same after injury and Andre Silva had lot of injury problems as well.
