10 isn’t dead exactly, it’s evolved in my opinion.

Out of possession, a lone striker on his own is easy to pass through, so ideally you want a 2 or 3 player front line out of possession.

The De Bruyne + Haaland link was originally formed with De Bruyne playing as a ‘10’. However, Haaland would cover the Left, De Bruyne the right. So out of possession it formed a 442. This made it seem like he wasn’t playing as a 10, as he was playing most of his time on the right, trying to whip that back post pass in to Haaland.

It was more like a false 9 role given how he was positioned in the press, but more or less a 10 in possession, which is effectively what a false 9 is.

From my understanding Matip ain’t played international football for a while, I think he’s effectively retired from it.
