If there's any chance he joins in January then get it done Txiki... to those concerned with him being backup, does he really have to be? We all know Rodri has the skillset to play further forward so both could play at times.
We'd better get a song in the works just in case, here's my piss poor attempt in blue already.
In brackets are alternate lyrics for next season if all goes well.
Martin Zubimendi, where are you... You've got to help with Rodri.
Martin Zubimendi, where are you... the dippers thought they signed you.
Martin Zubimendi, I see you...
Right next to Bernie Silva.
(/Sitting deep you and Rodri)
(/Sitting deep you and <insert name>)
All our rivals now are sat in tears... they can see you cover Rodri
(/They can see you're next to Rodri).
Martin Zubimendi, we'll love you... If you'll only help our 5 peat.
(/Martin Zubimendi, we love you... You helped us win a 5 peat)

Now that horror song is out of the way...
Zubimendi could be a fantastic signing not only short term but a long-term fix in case of injuries too, not only would he fill in for Rodri but when Rodri is back he can return and play further forward at times.
It doesn't have to be one or the other every time as we all know Rodri can do anything a box to box midfielder can, there can and will be games where we have both (if Zubimendi joins) players in the starting XI as Rodri can operate box to box.
