Aston Villa are monitoring both Nicolas Jackson and Alejandro Garnacho, talkSPORT understands.
Unai Emery previously managed Chelsea forward Jackson during his tenure in charge of Villarreal.
The Senegal international scored three goals in 27 appearances during their time together.
He was also handed his LaLiga debut by Emery in 2021 at just 20 years old.
They could now be set for a reunion as Villa look to finally replace Jhon Duran.
The Colombian completed a move to Al Nassr at the end of the January transfer window, with the deal occurring too late for a new striker to be brought in.
Duran has since moved to Fenerbahce but already appears to be in trouble with new manager Jose Mourinho.
Jackson has been attracting interest this summer with his Stamford Bridge future currently uncertain.
Although he has eight years remaining on his contract, the Blues have already signed two new forwards during the transfer window.
Both Liam Delap and Joao Pedro have joined Enzo Maresca’s squad, with the pair playing key roles in their Club World Cup triumph.
Meanwhile, Jackson did not make a start after Chelsea’s tournament opener, playing just 30 minutes in the knockout stage.
As a result, Manchester United have also been keeping tabs on his situation.
Meanwhile, Villa are keen on current Red Devils star Garnacho in another potential addition to their attack.
The 21-year-old previously fuelled links to Villa after sharing a snap to social media wearing the club’s shirt with Marcus Rashford’s name on it.
Garnacho is understood to have asked to leave Old Trafford this summer.
After five years with United, the Argentinian could now be allowed to leave by Ruben Amorim.
It comes despite 11 goals and 10 assists in 58 appearances across all competitions last season.
Only Bruno Fernandes scored more goals for the club during a disappointing campaign.

As for Villa, Emery has already made two additions to his squad ahead of the new season.
Dutch goalkeeper Marco Bizot has joined the club from Brest to challenge for a place between the sticks.
Meanwhile, teenage defender Yasin Ozcan has arrived after his move from Turkish side Kasimpasa was confirmed in February.
