Marchisio is definitely not untouchable. But I'd keep him in the team, unless he's the only thing keeping us from a top striker, and honestly, he shouldn't be. I'd rather sell two of our current forwards than marchisio. He's a big part of the reason our midfield is one if the very best. And it's not always about having the best players in a team, but rather having the best combination of players. marchisio fits well here, and him leaving would definitely leave a void in the team
