Genuinely hopeless post.
He's played one game.
"Should never have been signed at all" but also references "long term" later in the post.
That isn't how it works. This is what you need to understand.
The squad isn't built for a manager if you have a DOF. That is the exact mistake that the club made for years before appointing Paratici. When you have a DOF they build the squad and then bring managers to work with it.
You may have noticed the praise that Brighton get for being able to bring in De Zerbi after Potter or being able to lose Bissouma and Drossard without feeling it. It's because they don't operate in the dinosaur understanding of football management that your post displayed.
Porro (like Udogie and Spence) is a squad purchase, not a manager purchase. He's not going to be converted into a full-back because it would be incredibly stupid to buy the best RWB available on the market and one of the best in the world, then change his position.
As for saying it's terrible recruitment after 1 game...Have a word with yourself.
