Just threw this together. Obviously, I had to guess at the wages, but I reckon they're all in the right ball park, enough to prove my point anyway.
You can see why the owners might not rate him as highly as we do.
He has only been here 4 full seasons and two half seasons (2005 and the current). This would be equivalent of five full seasons, which would bring your spreadsheet numbers up to 17 or maybe 18 PL games per season ....... just to point out that your numbers are wrong.
Furthermore, like I said earlier, he has played on average nearly 30 games per season (in his four full seasons here 2006-2010) many of which have been important CL games. No matter how everyone feels about the PL, the CL is kindda important to this club.
And another point. We really have no idea what the guy is earning ....
Good luck finding a replacement of his quality and in this price group ... it is not possible I tell you.
btw, can money and spreadsheet calculations put a number on this guys commitment for LFC?
He has played games with broken limbs and do you remember him heading several balls away ag. United when he had suffered a severe concussion?
He is always giving us a 100% when fit and playing. He loves the club and city from a pure heart. Try putting a number on that. mate
