I just had a look at transfermarkt quickly. Some of the players listed are Morata etc, most other clubs couldn’t afford to loan out players bought for that amount.Your first sentence is very important I think. If you are a kid with so much talent that you are bound to become a top player and confident to boot then you might decide to stay at your existing club and develop but if you are just a good young player in a less wealthy league and have, like most young footballers, come from a poor or even ordinary working family then a Chelsea contract sets you and your family up for the rest of your life.
At eighteen a four year contract on 10k a week earns you £2 million by the time you are twenty two or £52,000 for forty years, it has to have a bearing on a kids decision, it would mine in their shoes.
I reckon your valuation is a pretty conservative one actually, 42 players on loan with an average of £10mil is over four million and £10 mil is a pretty reasonable price in this day and age. I wonder if anyone has realised the significance of that by the way? Chelsea have been using it as a meat market sideline for years now but the other side of the coin is that if Abramovitch does decide to get out selling those players is a pretty simple way of turning your assets into money with which to repay some of his loan to the club
These players being sold might be the indicator if he is to sell the club
