Good post mate, i know where you are coming from we are all coming from the same place. Im not sure there is a blanket answer, each case requires a strategic response. Cenk definitely has a market value, we have offset some of his cost this year, by a loan fee and i assume Palace picked up his wage while on loan - in not sure what that situation is now he is injured. I think we will sell for money eventually, so id sit on him until fit. he could go to the Euros (whenever they happen) and have a stormer - he usually does for Turkey.
Similarly Bolaise, hes had three loans now and we would have clawed some finance back on fees and wages. His book price is minimal now anyway, so real money would be great for him, its whether he would move of not - hes on the contract of his life - if he was offered a deal elsewhere for years it might be prudent to leave for longevity.
Sandro i can see being rinse and repeat we are offsetting cost with him best we can, loaning him out elsewhere taking a percentage of the wage.
The difficulty is releasing these lads, we are liable to pay up the remainder of their contracts as we want to break them. Like when we sack a a manager they are entitled to a pay out for the remainder of their contracts.
If it was as straight forward as just releasing these lads, football would be awash with released players every window, every club has a few.
Unfortunately are only option may be to bide our time with some of them.
We need to be so much more clinical in our transfer dealings, I can't help thinking some of our past purchases has been buying for the sake of buying. We cannot afford any more Niasse's or Sandro's for quite some time.
I know I may have a very simplistic view of things but I would draw up a list of positions which we need to strengthen, I would weight these in terms of importance and then identify maybe three players to go after in each position. If we were unable to get one of those three then I would move to the second position and leave the first until a later date. The skill would be in weighting the positions in order and deciding who we go after.
I don't believe we can bring in the players we need unless we shift quite a few on.
