Depends 100% upon which forward you're criticizing, and which poster is replying to you... Some are utterly infallible, and others are utterly unredeemable. Anybody who cannot acknowledge that Mo HAS scored some important goals this season whilst ALSO being clearly not the player that he was a 2 or 3 years ago, just cannot be reasoned with.
Today, all but two things he touched turned to shit... Now, one of those two things was the winning goal, so the inevitable "Told you so" started. But, he IS clearly declining, that cut back & aim for the top corner NEVER works anymore, no matter how often the commentators pretend it still does, and his speed is no longer a factor in keeping defenders honest with him.
He is still scoring tons of goals, but he's also very often the reason our attacks break down. We DO go through him far too often (a la Stevie G, as somebody mentioned earlier), and, though of course we'd miss his 25 odd goals if we did sell him, you'll never convince me that THIS Salah is not far more replaceable than many claim. The others did fine without him, and the money we'd get could be put to very good use elsewhere.
Today's game was a perfect example of what he's become this season, the good and the bad...
