Chelsea have become renowned in recent years for their use, some would say exploitation, of the loan system in football.

At any one time the Blues can have over 30 players on loan, with many being sold on for profit and a select few coming back to the side as fully developed young footballers.

Pre-season has allowed many of Chelsea's young players an opportunity in the first-team, with most getting their first taste of senior football - and no doubt many are keen to continue this going forward.

The reality is that at a club like Chelsea, first-team opportunities for youngsters are hard to come by - and so in order to get experience many will be forced to leave the club this summer on a short term loan move.

With that, here are THREE players that MUST leave Chelsea on loan this summer...

Kenedy

Can Kenedy thrive under Conte next season?

Kenedy's exclusion from Chelsea's squad last weekend in their final pre-season game speaks volumes about his current role in the Chelsea side, and for many fans it will be disappointing.

For all the young players that have been given a chance under Antonio Conte during pre-season, Kenedy is one of the few that will feel hard done by. He looked good last year in bursts, and under Jose Mourinho he was a fully fledged part of the Chelsea first-team.

That doesn't look set to be the case for the young Brazilian next season, and as a result Kenedy must go out on loan. To be honest, the move does make sense; he is now acclimatised to life at Chelsea and in England - it makes sense for him to go away and play for a side week in week out.

If he does that; he will no doubt come back and be a star with the Blues.

Matt Miazga

Antonio Conte has already revealed that Miazga will go out on loan over the next week or two; and the deal definitely makes sense.

He was never going to become a key part of the Chelsea set up at this point, with the young American looking very raw in back line in his few appearances.

He has all the ability in the world; he just needs to develop it by playing each week.

Expect him to go on loan to a Championship side and impress, before an inevitable return to Chelsea next summer.

Ruben Loftus-Cheek

This one will upset a number of Chelsea fans; but Ruben Loftus Cheek MUST go out on loan next season.

This one will almost certainly not happen; but it makes the most sense out of any deal.

Despite his promotion to the Chelsea first team, Loftus-Cheek has done very little to prove that he is even close to the quality needed to play for Chelsea. He has looked good in bursts; but Nathaniel Chalobah has come in during pre-season and outshone his English compatriot.

He looks built for the Premier League, but he needs a season playing where he can enjoy weekly football - he won't get that at Chelsea. If he wasn't English; we don't think Chelsea fans would want him playing each week!

A season away will do Ruben wonders.
