The difficulty, as it is with the striker role, is that world-class holding midfielders do not come to be sat on the bench. Rodri is the world's best holding midfielder, as Erling would be most people's pick for the best striker. The reality is that we need someone to replace Berni, who is capable of playing the CDM role, and to play alongside Rodri, or in his place. That is not easy to fill, but we will, and will need to be patient because nobody in world football will come in for Rodri and be him.Our midfield being bypassed has always been our Achilles heel to a greater or lesser extent. We need a top level holding midfielder in the summer.
