Bielik is coming out of his best full season with Charlton and had a very good Euros with Poland.
He is home-grown and has 2 years remaining on his contract at age 21. He can play CB but was good at DM with Charlton.
Mavropanos hardly played for us.
He is 21 and has 3 years remaining on his contract.
He has shown some glimpses of true defending talent when he played but also had some rash and hairy moments.
He has been injured for a while now and needs to get fit.
We all know about Mustafi. He joined in 2016 and has failed to live up to the expectations we had of a World Cup winner.
Whether we play a back 4 or a back 5, we need at least 5 CBs. Sokratis, Holding and Monreal already make for three. Surely a CB will be brought in to replace Koscielny. There is one spot left, so… who should it go to? Bielik, Mavro, or should we keep Mustafi?
Have your say and explain your reasoning.
