Chelsea boss Avram Grant is delighted with the way the early weeks of his Blues reign have progressed.
Grant declared: "It was not difficult for me, it was a challenge. It was very interesting for me. I have been coaching since I was 18, first with youth teams, then with teams in the (Israeli) Premier League, then the national team.
"I followed many games and many training seasons for the last 30 years all over the world, especially in England, because in Israel everybody supports an English club and I came as a director to build a team at Portsmouth.
"So from one thing it's a great honour to be manager of Chelsea, but on the other hand, it's the first time in my life that I have had to take a job like this in the middle of the year.
"I think my strength is that I like to create something from the base, step by step. Here you need to do it but in a very short time, you have a game every four days. I wanted to bring a good result but I wanted to do it in a different way.
"I don't mean the way before wasn't good but it doesn't matter because each coach has his own way. So it wasn't easy but it was a challenge."
Grant also revealed that the squad he inherited from Mourinho has adapted to his new methods of training and a more attacking style of play quicker than he ever thought they would.
Grant added: "They have adapted more quickly than I thought. Because if you take a team like Barcelona, since (Frank) Rijkaard came it took them more than one year to play this well.
"Arsenal for the last two years have not played as well and with Man United it took (Sir Alex) Ferguson three years. I haven't got this time. I need to do it in a very short time, which I like, because all my life I was looking to create something and I think we did it very well.
"So it is much more quick than I thought, but there is a lot to do to put Chelsea in the right side of football.
"Any coach that finishes a school of football knows how to organise a defence, but not every coach knows how to play attacking football.
"We try to do it at Chelsea. I think we developed very well in a very short space of time, but I think we will also have our difficult days. Also we will learn from ourselves and we develop our game because you need to remember that to the respect of Chelsea, before Roman Abramovich took over the team, it was not a big team.
"It is not like Real Madrid or Barcelona, but I believe that it will be like this. You can't fight with this, they are big clubs and Chelsea was not. This is a fact. Before Roman took over the team, it was not a big club. Now it is one of the best but we can make things better."
