Speaking to reporters, the former Chelsea boss said, "We're working on new signings. We will hopefully improve the squad in winter. It's not going to be easy because the January window is always more difficult than the summer. But at the same time, we'll trust the quality we have.
"Maybe we'll need two new players, or if it's someone that can play several positions, then maybe one would be enough if we are spared injuries. We know it's difficult to get players in January. We will need patience and optimism."
