#3 Tammy Abraham
A Chelsea academy graduate, Tammy Abraham has been among the goals in almost all of his loan spells. It wasn't long before he made his debut and was later handed the no.9 to lead the attack under Frank Lampard.
He finished his first full season at Chelsea as the club's top scorer and everything ticked up for him to remain the Blues' frontman for the long term. However, things went downhill when Thomas Tuchel became head coach last season.
Abraham fell down the pecking order behind Timo Werner and Olivier Giroud, scarcely featuring on the pitch, but still finishing as the joint-top scorer for the season.
Tuchel's Chelsea went onto become European champions but their woes in front of goal continued and a new targetman was prioritized for the summer. Following Lukaku's transfer, Abraham signed for Roma in a £34m deal.
A buy-back option of £68 million, which can only be triggered after two seasons, has been inserted into his contract with the Serie A club. It indicates the possibility of a way back for him to return to Chelsea in the future. As Chelsea director Marina Granovskaia said:
"Tammy will always be welcomed back at Stamford Bridge as one of our own. We have all enjoyed watching his progress through our academy and into the first-team squad, and are grateful for his contribution to our successes at senior and youth level."
Don't think there can be a clearer message on how much the club values him and can activate the clause in time. Abraham will surely be willing to prove a point at Stamford Bridge if he gets a second chance.
#2 Valentino Livramento
Chelsea's Academy Player of the year for the 2020–21 season, Tino Livramento, has been tipped for success at senior level. Despite not making a senior debut, the 18-year-old right back was already on the watchlist of several top European clubs last season.
With only a year left on his contract, Livramento was concerned about his chances of clocking regular first team minutes at Stamford Bridge. Chelsea had also shown strong interest in signing Achraf Hakimi, who later joined Paris Saint-Germain, back then.
After failed contract extension talks, Livramento decided to pursue his football elsewhere. Southampton secured his services amid interest from clubs like Brighton, AC Milan, Aston Villa and RB Leipzig.
Despite not playing a single minute of top flight football, Chelsea raised a fee around £5m for Livramento, even inserting a buy-back clause of £25m.
Livramento has featured throughout the entirety of Southampton's two games so far this season and looks set to enjoy regular first-team football. If he does live up to his glaring potential, Chelsea could be tempted to activate the clause to lure him back to Stamford Bridge.
#1 Declan Rice
Having joined Chelsea's academy at the age of seven, Rice was released when he was 14 and moved onto West Ham United's academy. It wasn't long before he was playing for their first team. Since then, Rice has become one of the most sought after defensive midfielders in the Premier League.
A regular in the middle of the park for England throughout Euro 2020, the 22-year-old has courted serious interest from Chelsea. N'Golo Kante's injury troubles over the past few years have highlighted the Blues' need to bring in a midfielder of the same profile who could replace the Frenchman in the long term.
Although Tuchel has maintained an interest in signing Rice, West Ham's valuation has been deemed excessive by Chelsea. Rice is valued at around £100m which mean Chelsea will have to spend some big money if they are to price him away to Stamford Bridge.
Manchester United have also expressed their interest in Rice and so it won't be an easy task for Chelsea to sign the young England international.
One can expect large bids to be coming in for Rice very soon, who has a contract with the Hammers until 2024.
However, it feels as if Rice will eventually move on from West Ham and his former club Chelsea are expected to be involved in the race to land him in the future.
