Who else are you going to play? Its not like Saele is any better and the left with Rebic playing shit and Leao out isn't exactly overloaded either.
He could have startet Hauge instead of Krunic but that's about it.
saele is way better than castillejo, castillejo runs his head off and always gives his all, i can appreciate that, but he achieves nothing with it..
Seriously, re-watch castillejo and his games and focus only on him. like 95% of the time he gets the ball in attack, he just loses it randomly or takes too long to do something with it and has to pass back again.. Same goes for Krunic, gives his all but he is just so limited.
Saladmaker on the other hand - while having his flaws at least has some signs of decency..
Rebic isnt the Player some wish him to be (sadly) but he also has a lot of genius moments that lead to goals. His problem is constistency and not skill (as so often with talented players) while krunic just lacks skill at all..
So playing Rebic and Saladmakers on the flank in the game against sampdoria would've made a huge difference, you can clearly see the difference to the game against parma where does 2 started...
Kalulu can cover for calabria this way, instead of having to play saladmaker out of position, like he did against sampdoria..
Nonetheless, Pioli is the best Coach that we had since Ancelotti - no Allegri wasn't a good coach for us and also a cause for many of our problems we had to endure the following years (things like buying matri that cost us for years).. I think some decisions from pioli are questionable (for example lineup against sampdoria and the 2nd match against inter) but the man gets like 85%-90% of his calls right - we only complain if something doesnt work out... thats a great number and if some things did go more our way (first roma match & first hellas verona match this season) we might even still be in the title race...
All in all i hope pioli stays - no matter how the season ends - and learns from the mistakes he made this year. Then we'll be real title contenders next year
