Rafael Benitez today confirmed Chelsea were looking to bring in reinforcements in January, saying cryptically: "We'll see if there are any surprises."
Oriol Romeu's season-ending injury has left the European champions short of holding midfielders, with their only other recognised player in that position, John Obi Mikel, on African Nations Cup duty next month.
Speaking ahead ahead of tomorrow's Club World Cup semi-final against Monterrey, interim manager Benitez said: "The club is working and always looking for good players, so we'll see if there are any surprises."
"Oriol Romeu was bad news and we weren't expecting something so serious," he said.
"He'll be fine for the future, he's a young player."
