As far as transfers go, we have in theory upgraded in several areas. Whether that remains to be the case, we can discuss in a few months or so.
1) Brkic > Glykos
2) Matos > Skondras/Kitsiou/Konstantinidis
3) Crespo > Vitor/Chatziisaias
4) Varela > Vitor and Chatziisaias
5) Shakhov > Golasa
6) Mak > Djalma ??? This one will be interesting. I don't think Djalma will be better than Mak. Just different. I don't think they are the same sort of player, but overall, if I had to pick one, it'd be Mak. I really believe with his explosive pace and Ajax's high defensive line, he would've wreaked mayhem. Oh well, it is what it is.
7) Canas. I'm expecting good things. He's meant to have a very high work rate. Could be the replace for Kace.
8) Biseswar, I don't know. He looks like he's gained weight instead of losing it,
