It obviously was a hard decision and one that wasn't the nicest thing to have to take.But it wasn't that tough to make up my mind because we were quite far apart in what we thought.
It wasn't necessarily something that Miles wasn't bringing. We had a chat when we were in Miami about how we saw things. We all saw things pretty differently.Between the three of us we obviously had different ideas and different ways of seeing things, what I felt was beneficial to me and what Miles and Alex felt was beneficial to me.
I need to be comfortable in the set-up that I have - have 100% confidence that everyone that's working with me believes it's the right thing to do.The last few years have gone very, very well, but I want to try and get to number one in the world and try to win Grand Slams.
It's easy to start over-thinking things and over-analysing things. I don't think there's a problem with my game.I just need to get better, and that's something that maybe hasn't happened the last four or five months.Hopefully by getting a new coach and a new coaching team in place, that will help me do that, and hopefully achieve my goals.Now I feel good again. I feel confident after the way Wimbledon went. I kind of saw what the problems were, what I needed to do to get back to playing top-three, top-four tennis again. I addressed it.
