General play isn't that good? What player have you been watching? He regularly leaves defenders on their arses and is our top assister too.
But I would take Dyballa and about 150 million for him. Or 300 million. This is record hholder for premier league goal scorer we're talking about, and he'll likely be in the 30 goals range this year. COutinho went for 150, having won nothing and with numbers not even close to that. If Juve aren't keen on that price, shop somewhere else.
I think you're referring to the Salah of last season. Aside from his goals, his gameplay has been below average this season. He used to pick up the ball and I'd be certain of either a goal or a shot on target. Now, you can be virtually sure he'll lose possession or make a bad decision. Where has his strength gone!?
He's the same player. Teams are treating him differently now, but he's producing very similar numbers. He averages 2.2 successful dribbles a game (2.1 last year) 3.3 shots per game (4 last year) gets fouled .9 times a game (.8 last year) makes 1.9 Key passes a game (1.7 last year) and loses the ball around 3.3 times a game (2.6 last year). Some areas are marginally better, some are marginally worse. There's not really a lot of difference.
He may not quite match that record goals tally, but he'll comfortably score around 25+ and he's on course to get more assists. Even though he didn't score against Watford, he destroyed their right hand side. The reports of his demise have been very much exaggerated. He's the best attacking player in the league, and he's likely to win the golden boot two years running. If Juve want him, they better be ready to spend a ton of money. He's done more than Neymar's done in a single season, and he's still only 25.
