Brazilian striker Pato has been spotted at Stamford Bridge fuelling rumours that the Corinthians striker could join Chelsea in January.
Pato has been linked with moves to Tottenham and Liverpool as well.
The Brazilian striker attended Chelsea’s Champions league game against Porto last night.
Earlier this season, the Brazilian was offered to Chelsea and it was reported that the Blues could sanction a cut price deal for the former AC Milan man to bolster their attacking options.
