Every season, Chelsea searches the transfer market for new additions to their already impressive group of stars whilst neglecting the players brought up within their youth system, some of whom are quite capable of adding depth and value to the first-team set-up.
On that note, here's a look at some of the best players Chelsea have sent out on loan primarily based on how they've performed this season:
Whilst still actively playing in Chelsea's youth ranks, Tammy Abraham was highly-rated by Chelsea fans and coaching personnel alike,he was one of the few with a solid chance of actually breaking into the first team set-up, but ever since his successful loan spell to Bristol City, he's hardly been considered for selection by the club's first-team.
In a bid to aid his development, though, he was sent out on loan to Swansea last season, and Aston Villa at the start of this season, and so far, he's become a fan favorite of Villa fans, scoring 5 goals in 11 first team appearances for the 11th-placed Championship side – proving he's reliable in front of goal.
He found the back of the net in Villa's 3-0 win over Derby County, in addition to the clever runs he made throughout the game to open up space.
After his loan spell he could feature as a back-up striker for the Blues considering Olivier Giroud is not getting any younger, and how much it costs to sign lethal strikers.
Fikayo Tomori has been able to garner some great experience being an integral member of Derby County's back four. He's become an important first-team player for the Championship side, thanks to his expert positioning when facing a goal threat from an opposition player, as well as his ability to pass the ball out of the back.
The 20-year-old is not ready to be a part of Maurizio Sarri's plans, though, mostly due to the quality and experience of the defenders currently within Chelsea's ranks and out on loan to other clubs, but considering the rate at which Tomori is currently developing, he's likely to be a Premier League defender in the next few years, be it at Chelsea or another PL outfit.
Often described as a wonderkid, 19-yer-old Mason Mount is currently on loan to Frank Lampard's Derby County who currently sit just 5-points away from top spot in the Championship, and Mason Mount, with his sublime displays for his loan outfit, has contributed to Derby's fine start to the campaign.
The youngster managed to earn a call-up to Gareth Southgate's England side just last month, which more or less validated his growing stock in football.The midfielder has scored three goals in 15 Championship appearances, created a total of 34 chances, and made 10 interceptions this season. Considering his age and the pressure on Derby to secure promotion, those are solid numbers.
He could become a good back-up option for Chelsea come the end of the season and potentially grow into a more significant role in the middle of the park.
Kurt Zouma spent last season on loan at Stoke City, where he put in some great performances before the Potters' relegation from the Premier League. Being a defender, Zouma did the best he could for the club, but there's only so much one centre-back can do for a relegation-threatened side.
Most recently, Zouma put up an impressive defensive display against Brighton as he tracked runs, and prevented Brighton from advancing further into Everton's 18-yard-area on a number of occasions.
The Frenchman still has some developing to do, but even now, he's capable of playing for Chelsea and doing a great job in defence, he could really help Chelsea out as a rotation optionbefore potentially replacing the ageing David Luiz.
Considering he's out on loan in the Serie A, a league as tough as the Premier League, and playing for a side with Europa League ambitions, in the form of Torino, Ola Aina is most definitely in a competitive environment, and he's making the most of it thus far, having taken the Italian top flight by storm.
The 22-year-old was named the man of the match in Torino's recent stalemate against Fiorentina having played exceptionally well in that game. He's also impressed Walter Mazzari, so much so, that Torino are interested in securing his services on a permanent basis – Chelsea, though, would be wise to keep Aina after his loan spell, as he's evidently ready for top-flight action, he just needs a chance in the first-team set-up.
