My point is that you can't overlook how inefficient Suarez is. At some point, taking over 8 shots to score a goal is going to come back and bite him(heh), regardless of his brilliance on the ball. It's a stat a lot of people overlook, and there are a million excuses for it, but a lot of his success came last season more from volume of opportunities. I wouldn't be too broken up with selling him at this point, because he's likely never going to see that volume of chances with us ever again, and unless he really kicks his game up a notch, his counting stats will suffer, and value will go down quite a bit.
You can score all the goals you want and make all the highlight reels, but would you ever pay 40M or 50M or whatever for a player who converts at such a low pace? Unless he becomes 20-30% more efficient, which is asking quite a lot, it's not a practical number to work with for a side looking to retain possession and compete in UCL. If he played as an AM or a winger that might be ok, but if his primary talent is scoring goals, it's scary to think how his ratios(and counting stats) will drop if his form dips.
