'Yesterday I talked fully to the squad about the past. I said why I was here and I want everyone to look either here or at home in the mirror and see what everyone can contribute to the way up . Not to look back so much. We cannot ignore what has happened in the past. I told them to be professionals and look forward.
'I want to make my own judgement by observing on the pitch, in training and inside the locker room. They have to show what they are capable of. I cannot see how the key players have a lack of desire or confidence at the moment. I cannot complain about the players.'
The 69-year-old, who managed the Blues in a similar role in 2009, admitted the club shouldn't be in this scenario after struggling this season.
The manager also showed sympathy for former boss Mourinho, who was relieved of his duties after winning the Premier League last season, and suggested he shouldn't have had to be called uponWell I wanted to start with a short introduction but I shouldn't be here half way through the season. It means things are not going well,' he added.
'I'm glad to be back, it was a few years ago when I came here in a similar situation. I'm here and it is the reality of the situation. To work with the players is always a pleasure.
'If you look at his [Jose Mourinho] record. I don't know by heart what he won but I have a lot of respect for that.People take decisions which they have taken and I have to go on when asked but theoretically I should not be here, it's true.
