Critics have attacked Chelsea in the past for a lack of faith in their younger players, and in some respects they are correct. The time spent scouting and investing in new talent has at times gone to waste, with the likes of Miroslav Stoch, now at Fenerbahce, never given a real chance of progressing despite their obvious ability.
Even now, the Blues have an astonishing total of over 25 players out on loan, with around half of that consisting of players who are at top-flight clubs.
