Top 5 on-loan stars that are killing it this season

#4 Tammy Abraham (Swansea City - on loan from Chelsea)

Tammy Abraham has been a crucial figure for Swansea City this season

Very few people knew who Tammy Abraham was last season. Just another product off of Chelsea's infamous assembly line of teenage loanees available on the cheap for second and third tier English clubs.

But 4 goals for a struggling Swansea City and an England call-up later, he's beginning to turn a few heads.

His superb return of 23 goals from 43 matches for Bristol City convinced the Swans to replace the departing Fernando Llorente by signing the 20-year-old on loan.

Antonio Conte recently hailed him as "a really good prospect for Chelsea's future." This bodes well for the youngster, who might well become one of those very few Chelsea youth stars who actually make it into the first team.

With Alvaro Morata and Eden Hazard being in incredible form, and with Batshuayi proving to be useful on more than one occasion, it does seem as though Tammy has his work cut out for him. But he's been doing the right things so far.

Certainly, one to keep an eye out for in the future.
