Moeen Ali admits he feels "comfortable" being part of the England set-up and is now "more of an all-rounder" than when he first broke into the side 14 months ago.
The Worcestershire player admits the development in his bowling has helped to cement his place in the side.
Moeen has taken 16 wickets in his last four Tests – all of them won by England – and that includes being given just the one over in the final Test of last summer against Indian.
His quickfire three wicket burst polished off the West Indies second innings in Grenada this weekend as England cruised to a nine wicket win.
Moeen said: "It has been a great year in terms of how many games I have played (for England). I didn't expect to play so much but I feel I have developed as a player, as a spinner.
"I feel very comfortable and settled in terms of me a person around the guys. At the time you're fresh to the squad and you don't know exactly what is going on and you're a bit shy.
"The bowling has almost been a revelation to me. Even in the one-day stuff it keeps me in the side as an opening batter.
"I feel more of an all-rounder now than probably a year ago. "I still feel there's a lot more of my batting to come. I just haven't justified it. Adapting to Test cricket is not as easy as people probably make it out to be."
Moeen struggled to show his best form in the first innings of the last Test after returning from the side strain suffered during the World Cup.
He said: "I felt like I was ready but the pressure of Test cricket and bowling at good players was completely different.
"I needed to bowl well and probably forced it a bit.
"The last couple of days, I spoke to Peter Moores and Paul Farbrace and they just told me to relax. That's exactly what I did."
It was a boost to Moeen to be brought straight back into the side after proving his fitness for Worcestershire against Yorkshire.
He said: "Myself coming straight back into the side after injury, the confidence it gives me knowing England want me to play is good."
Moeen is also convinced England are heading in the right direction.
He said: "It's going to take a bit of time but I feel the nucelus is there.
"We have some very, very talented players and a lot of people around the world know that we can be a dangerous side.
"We need to play and keep developing."
