Not seen him myself but by all accounts he isn't that special. If that's the case i'd much rather keep Mangala. His physical attributes are tailor made for the premier league, he revels in physical battles against big brutes like Kane,Costa,Lukaku etc If we play 3 at the back i really think having him as part of a 3 could make us almost impenetrable. You need defenders that complement each other to deal with all kinds of attacks, we don't currently have anybody like Mangala. I don't think Pep wants him around but this could be one where our hand might be forced if we can't get rid and don't have the funds to bring in a striker and defender and if that's the case i believe it would be a blessing in disguise.
