Pato only managed just one more appearance during his very short run with the west London club s the rest of the injured players return to action.
The former Blues has admitted that he had got more game time, possibly to prove he had what it took to maintain a first team spot.
However, this what not to be as Hiddink made it clear from the start that he was a back-up player.
“I wish I had played more, but I understand,” the Brazilian said of his time at Stamford Bridge.
“Twenty days after I arrived, everyone who was injured returned. And I was the last one, had just arrived. It was not what I expected, but it passed.”
Pato, who joined Villarreal on a permanent deal in the summer, admits Hiddink made it clear from the start that he was a back-up player.
The 27-year-old added: “Guus was very correct from the first day. When I arrived, we talked a lot. Chelsea had two or three players injured.
“Guus told me: ‘Look, Pato, you know there’s a hierarchy here, we have rules. You’ll be here, and I’ll give you a chance when I can.’
“I went to Chelsea with an illusion that I would play and show more, so maybe I could stay longer.
“Unfortunately I wasn’t able to play what I could have played. In the two games I played, I showed my football, I scored on my debut.”
