If I were Madrid I’d take this an opportunity to refresh the squad. In a heartbeat. With the money that United, Bayern, and no doubt PSG would find a way to spend on Cristiano, Madrid could fund deals for Mbappe and Lukaku. I’d much prefer them in the squad next season and for years to come than the 33 year-old and upward version of Cristiano.
You could hand over the attack to Bale in complete comfort that you’d have more than enough in reserve should he not be able to get over his injury issues.
