John Stones has revealed the tough nature of playing under his former Everton manager Roberto Martinez, despite the centre-back “doing everything right” during tough periods.

England defender Stones signed for Manchester City for a reported fee of £47.5 million earlier on in the summer, making him the world’s second most expensive defender.

The Toffees suffered a disappointing Premier League campaign last term finishing in the bottom half, which led to the sacking of Spaniard Martinez.

Stones, 22 was part of a Premier League defence that conceded 55 goals in 2015/16, compared to 59 goals scored.

But since his move to the Etihad the England youngster has revealed how his former boss completely changed the style of play prior to his sacking.

“It was a tough period because I was doing everything right,” said Stones as quoted by ESPN. 

“I was being professional, I was carrying myself well. I wanted to do everything right, try to get in the team how everyone should and fight for my place.

“I felt I was doing everything I could and deserved to play and still wasn’t. That’s when I found it hard. It’s probably a question you should have asked the manager at the time because he wasn’t telling me.

“Roberto had his style of play and kind of changed that towards the end of his career at Everton. He changed the whole style of the team and things weren’t working out at that time so you could say it wasn’t the best decision.”

Stones did not feature for England during the European Championships in France earlier on in the summer, as his home country were knocked out by minnows Iceland.

But the centre-back believes he learnt a lot about himself during his time at Everton, as he explained the tough nature of Martinez’ sacking.

“As you know, the gaffer got sacked. It wasn’t enjoyable,” said Stones.

“We weren’t winning games. When we don’t do that a few games on the trot, it starts to eat away at you, no matter who you are. It was a good test for me. I learned a lot about my football, about myself.”

“I felt it was right to move on to work under the best manager in my eyes.”

Stones has made five appearances for City boss Pep Guardiola so far this season in all competitions, and has settled in well, with the Manchester club winning all five games and keeping two clean sheets in the process.
