Alexandre Pato's loan with Chelsea has parent club Corinthians worried.

Reports suggest that the Brazilian side are anxious that Pato has not featured for the Blues and are concerned by the fact he only has nine games to prove himself in England.

Corinthians were hoping the 26-year-old forward would be able to find some form with Chelsea which would attract the interest of clubs around Europe and place a decent transfer fee on his head.

Pato is under contract with the Sao Paulo giants until 2017 but is almost certain to leave this summer, however, his lack of game time at Stamford Bridge would not have drawn any bids from previously interested clubs which has Timao slightly worried.
