The 21-year-old Atletico Madrid and Argentina star was heavily linked with a £40million move to Stamford Bridge during the summer.
Fresh reports have suggested that Chelsea are keen to sign the South American in January following his two goals during Wednesday's 2-2 Champions League draw with the Blues in Madrid.

"I know that people were saying they (Chelsea) wanted me during the summer and that there were several teams tracking me but nothing ever came to me and I am happy at Atletico," Aguero told AS.
"It's nice that people say I could play in a team like Chelsea, one of the best in the world.
"I like it and it makes me happy but I am the same person as ever and I think the same as before."
