You do understand that value is subjective and buyers and sellers have different view on value. To us Lewis is the heart and soul of the current team he fits in with our style perfectly to another team he might only be another centre back not the main man. Therefore he is more valuable to us...
Could be the all time record OG record holder in the Premier League, I am almost wishing for 1 more and I don't begrudge any of them, all unlucky and as a consequence of his never say die attitude.
I would not swap him for any other defender in the league.
