Probably the simplest solution of all would be to keep Ceballos once he returns from his loan spell at Arsenal.
The 23-year-old has impressed in the demanding Premier League, and has earned himself comparisons to an old Arsenal favourite in Santi Cazorla.
The solid performances in London, in fact, have won Ceballos a spot back in the Spanish national team. However, hopes of a return to the Santiago Bernabeu ultimately rest on Zidane’s final decision.
Incidentally, there have been rumours in the Spanish press that the pair don’t get along.
