"The players know that, after a lot of years talking about being contenders, this is a fantastic opportunity so they are really together and you can see the mentality of all of them. The training sessions over the past two weeks have been very good," said the boss.
"This season, from the beginning we were so good, we were scoring goals and winning games and everyone could see that it was an opportunity for us.
"People were saying, 'Maybe it'll be this year' so we have created a lot of the expectation ourselves. But we are still in this position so everybody knows that we have to do our best.
"Clearly we have to improve in attack. We have plenty of control and plenty of possession, but we have to create chances and take them. This is one area we can clearly improve on and we are trying to improve.
"We are in the best position that the team or club has been in for the last 15 years or something so we have to be positive and think about the positives, concentrate on Chelsea."
