With stars such as Nemanja Matic, Cesc Fabregas, Eden Hazard and Diego Costa at the club it isn't surprising that Chelsea have loaned out their youth talent for game time and experience.
But just how many of those 28 players sent on loan this season will end up playing for the Blues in the future. We look at the ones that have caught the headlines in previous months...
Lewis Baker - Vitesse Arnhem
Having signed a new five-year deal at Chelsea last August the 20-year-old attacking midfielder spent half the following season in the first team squad, with the second half on-loan at Sheffield Wednesday and MK Dons.

The England youth star will get more game time in Holland than he would have done in West London, but as the club already has Fabregas, Oscar and the financial flexibility to buy a world class midfielder it would seem Baker won't be making it into the Chelsea line up any time soon.
Patrick Bamford - Crystal Palace
The striker signed a new three-year contract this summer before being loaned to London side Palace. With Drogba leaving as a free agent at the end of last season there was space in the first team squad for the 21-year-old to compete this season.

But Mourinho opted for a season-long loan for out of sorts striker Radamel Falcao, this clearly shows that the manager and others at Chelsea believe Bamford is not yet ready for Champions League football.
With Palace splashing £9 million on striker Connor Wickham time will tell if Bamford can keep him out of a Premier League side before he tries to replace Diego Costa. However he could very well get his Chelsea chance next season with questions being raised over Loic Remy's fittness in providing backup to Costa when needed.
Isaiah Brown - Vitesse Arnhem
Having spent the entire of last season training with and being on the fringes of the first team squad you would be forgiven for thinking the 18-year-old would play more this season, yet he is just one of a handful of players sent to Vitesse to gain experience.
Regarded by Mourinho amongst the cluster of English talent at Chelsea headed for the England team or the blame would fall on him, showing that although he's on the loan this season there is high regard for the former West Brom man at Stamford Bridge, and with the first team lacking any real cover for Oscar in midfield a good season in the Netherlands would put Brown right up for contention next campaign.
Nathan - Vitesse Arnhem
Signed for around £4.5 million from Atletico Paranaense in mid-May the 19-year-old made his Blues switch on July 1 and was subsequently loaned to the Dutch side for a season-long loan.
The fast Brazilian offers creativity and a keen eye for goal, something that is needed currently at Chelsea but having barely played any first team football he needs at least a full season under his belt before he enters the fold at Chelsea. Expect to hear more of him in the coming seasons.
Dominic Solanke - Vitesse Arnhem
The 17-year-old has been with the Blues since he was seven and last season found himself training and on the first team squad fringe alongside Isaiah Brown.
A year loan would seem the right move for Solanke who is too young to contest Diego Costa, Loic Remy and Radamel Falcao but has outgrown the club's successful youth system.
The loan should see the 2014 England youth player of the year pick up some much needed experience as he seemed too raw when given first team chances last season, yet his great ball control and finishing has resulted in many believing he has the potential to one day start upfront for Chelsea.
It may be a few years before we see Solanke back at Stamford Bridge, but with Falcao only on a year-long loan he may find himself battling it out with Bamford for a spot in the squad sooner than we think.
