The thing with Azpi is that it is pretty obvious that his link with Morata is something that they practice off the pitch and what Conte looks to utilize in games, so that is a very specific situation where regression could be a bit less serious.
Alonso was also taken off early couple of times because of tactical reasons and I understand Conte, because Alonso, as much as he can be good for FPL, is not the best defender there is and his weaknesses are often exploited by the opposition, especially without Kante.
Azpi is far much better all-round defender, better in BPS and also looks to be more prone to rotation, although nobody will really be safe this season.
If you are on WC he still costs you 6.7 and should do enough to justify his price.
Regarding Burnley, they will probably not be able to continue like this, but should still do enough for their price.
