Mfuni's age is against him, of course, but he would be a third or fourth choice in that role behind Gvardiol, Ake and O'Reilly. If we buy another full-back like Kerkez, for example, then we accept that Gvardiol is now a LCB, which is probably his natural position. We also don't yet know how Hugo Viana intends to integrate the academy players.
I wonder if Pep's repeated comments about reliability hint at departures.
BTW, I watched a brilliant video about Rico the other day. It really showed his skill and movement in what it referred to as the 'half-space', which I would read as between the lines. I find it a shame that so many here don't appreciate him, or perhaps they are just a vocal minority.
