The fickle nature of football means players not featuring regularly are quickly forgotten: Bill Shankly famously made a habit of blanking players who were injured or unavailable. It is much the same with loanees. Who else will admit that they forgot Victor Moses was still a Chelsea player at the start of this season?
Mostly, players are loaned out because they are inexperienced or surplus to requirements, but occasionally a player such as Moses can return and be like a new signing. Who might be that man for your club next season?
