Since Roman Abramovich bought Chelsea in 2003, he has injected the London club with big money to buy players. The idea was to buy good players and build a team for the short term, while the long term goal was to bring in youngsters from the youth academy.
The plan was to develop and nurture young talent from the youth academy much like FC Barcelona. After developing them it was hoped they would be good enough to be in the first team and provide Chelsea's senior team with quality players in the long run.
In order to implement the idea, Chelsea bought in young players and sent them out on loan. If they performed well they were included in the first team. The prime examples of it being Thibault Courtois, Andreas Christensen, and Ruben Loftus Cheek.
But, in time it has become rather difficult for players to break into the first team. It has become a habit for Blues to loan out underperforming players as well.
It is clear that Chelsea have failed to achieve what they intended to do. Now with the transfer ban in place, they won't be able to register players for the next two transfer windows. Even if they sign players, they won't be able to play on the field for them.
This has prompted many to suggest that it might be time for Chelsea to use the players from their loan 'army'. It has been suggested that there are many players who should be given a run in the first team and it could help the Blues in this tough time.
The likes of Mario Pašalić, Alvaro Morata and Bakayoko have not been mentioned. These players have clauses in their agreement as per which they could sign for the loaned team next season if a particular amount is paid to Chelsea.
Thus, here are four players from Chelsea's loan army to watch out for next season:
#4 Mason Mount
The Englishman is on loan at Derby County where he has performed extremely well under the guidance of Chelsea legend Frank Lampard. The youngster is a creative midfielder and he only 20 years of age.
This season he has scored 7 goals and further 5 assists for the Rams. The midfielder has shown plenty of promise, as he was recently given his first England call up. He has also, caught the eye of the foreign clubs such as RB Leipzig as well.
Mount could get more chances next season, as Mateo Kovacic's loan spell coming to an end at the end of the season and Ross Barkley constantly underperforming. It might be the perfect time for Chelsea to introduce Mason Mount into their squad as their next midfielder.
The Chelsea loanee has already shown how important he to the Rams with his quality. Though he may not directly jump into the first team at Chelsea, but he could be introduced slowly to the first team like Loftus Cheek has been.
Given the amount of promise and form he has shown, a good run for him in the first team could help him establish himself as a regular.
#3 Tammy Abraham
Tammy Abraham is another Englishman who is at loan to newly-promoted side Aston Villa. The youngster plays as a striker and has a knack of scoring goals as well. He is known for his good technical play and movement around the box.
He is only 21 years old and he has Premier League experience as well with Swansea City. This season he has scored 22 goals for Aston Villa and helped them in their push for Premier League football.
The youngster could just provide a different option to the Blues. Morata is on loan to Atletico till 2021 and both Giroud and Higuain are underperforming. Thus, Tammy Abraham should be a good option going forward next season.
He has already shown that he is a proven goalscorer, but only in the Championship. Though it may not be as competitive as the Premier League, it shows that Tammy has the quality to potentially score 20 goals a season.
Since the departure of Diego Costa, the Blues has missed a striker who can reach that twenty goal mark. With Abraham's technical abilities he could be a good option for Chelsea going forward next season.
#2 Reece James
Recce James is on loan from Chelsea to Wigan Athletic. The 19-year-old plays as a right back, but he is also capable of playing as a centre back. He joined the Chelsea youth academy at the age of six.
This season he has made 39 appearances for Wigan and despite their struggles, he has still managed to excel. He has been delivering some wonderful performances and the Chelsea fans want to see him in the first team next season.
Currently, Chelsea have Cesar Azpilicueta and Zappacosta as their right backs. Azpilicueta has been a waning force and Zappacosta has failed to impress. Thus, it is no wonder that he is a part of Chelsea plans for the first team next season.
Recce is a like a modern-day attack-minded fullback and at the age of 19, his best days are yet to come. He is likely to improve with age and if he continues to perform he will soon be Chelsea's first team right back.
#1 Kurt Zouma
The Frenchman might have been a part of Chelsea's first team, had it not been for that unfortunate injury against Manchester United two seasons ago. He was a regular under Jose Mourinho as well as Guus Hiddink till 2016.
He is currently on loan at Everton where he has given very commanding displays. The former Stoke City defender is blessed with pace and good aerial ability.
Chelsea defenders have often struggled when exposed to pace, while Zouma should thrive under Sarri when they face counterattacks. He has plenty of experience as he has already made 70 appearances for the Blues.
The former Saint-Étienne defender has shown that he has what it takes to play at the top level. It was only because of the long term injury that his career got got temporarily derailed. The Blues must consider how good he was in the past for them and could include him in their plans for next season.
