"I`m doing some good fitness work. We`ll keep pushing it -- not too quickly, obviously -- but I`m really positive about it and so is the medical team."
Asked about his chances of featuring against Uruguay in Sao Paulo, he told British newspaper journalists: "We are not sure about timescales.
"We are hopeful that would be realistic, but there is nothing set in stone and I can`t say whether I will definitely be back or not.
"I am hopeful for that game, but there is nothing set in stone."
