Zonal marking works fine if it is implemented correctly and the players fully understand their roles. Our zonal marking is garbage atm. But we've played a different centre half and midfield partnership every game so the understanding won't be there yet. If in 10 games time we are still conceding the same awful goals then Silva is doing something very wrong.The reason we're bad in defence is because zonal marking is garbage
I'm not sure what the introduction of one player is supposed to achieve on that front if I'm honest
As for adding Mina into the mix, increasing the height and aerial ability to defend crosses will always improve our ability to defend corners.
