"It is practically impossible," he told a press conference. "That's too much [of a gap] at this stage. Last year we had a 10-point advantage in February or March and we were able to maintain it.
"I have never been in a situation like this, dropping so many points and with a team so far from its objectives. It's new for me. The league looks impossible to me now, but we have to have the dignity to always try to win."
