Arsenal boss Arsene Wenger has urged fans not to expect too much too soon from Eduardo after his brace last night against Cardiff City.
He told arsenal.com: "We will know how important this was at the end of the season. I am very happy to have him back because he gives us options. He can play on flank, he can play central, he can play on the shoulder or upfront on his own. It is fantastic for us.
"I still have to be cautious with him and I cannot throw him in every three days after nine months. We will see how he responds to that hamstring and maybe he can be with us on Saturday, I don't know."
