John Stones has given England a huge fitness boost and is proving his “elite mentality” ahead of the Euros.

Manchester City defender Stones took part in a full training session and will be fit for England’s Group opener with Serbia on Sunday. Stones, 30, had to go off at half-time of England’s friendly defeat to Iceland last Friday and was a major worry ahead of their Euros campaign.

But England team-mate Anthony Gordon says he has no doubt that Stones will play against Serbia and says his quality will be vital to their chances. Gordon said: “As I said after the match, I was a bit worried when he went down because he’s such a big player for us but he’s fine. He’s got an elite mentality, so I’ve had faith in him.

“It’s really important. We want everyone as fit and healthy as possible going into the tournament so we can perform our best.”

Full-back Luke Shaw did take part in the hour-long open session in front of around 500 locals in Jena which is close to England’s training base. But Shaw ended training wearing a green coloured bib to ensure no-one tackled him as he did not take part in full contact work and looks certain to miss the Serbia game.

But Gordon says Shaw is on the “right path” and said: “Yes, he looked like that. He’s back in training now and doing really well. I did a bit of my rehab with him and he was way far ahead of schedule. He was doing great, which is good.

“I’d love to start but I’ll be ready no matter what. What I‘m asked to do, I’ll be ready.” Three Lions boss Gareth Southgate, whose contract expires in December, has also admitted that he will probably leave his job unless he guides England to glory this summer.

But Gordon says the players all want him to stay. Gordon added: “From a selfish point I would want him to stay. I love working with him and his staff. From my youth journey with England, the way they have transitioned the whole set-up from youth to senior level has been absolutely amazing and I don’t think they get the credit he deserves.”

England players will not be told to shut down their social media accounts during the Euros. Some stars are ready to log out of Twitter, Instagram and their other platforms during the tournament to avoid seeing negativity and abuse.

Research in the past has shown there is a big spike in abuse during major tournaments and there are bound to be fears about a repeat. However, the Football Association are not planning any special guidance or advice.

England boss Southgate’s view is the players are experienced enough to make up their own minds. Harry Kane received the most abuse during the 2022 World Cup, receiving three out of every ten negative tweets.

England players were sent 1,546 abusive tweets during the group stages of the last World Cup, according to analysis by the Alan Turing Institute. Declan Rice shut down his social media account during the last Euros, saying he wanted to for us on the tournament.

Rice said: “I have just deleted Twitter, I did it after the Croatia game, nothing bad, I just thought, I like Twitter, I read stuff, I felt for this tournament it was best to come off it and just focus on the tournament and myself.

“Sometimes you can put doubts in your mind about your ability. I had to come off it, I am sure I will be back on it soon.” Bukayo Saka, Marcus Rashford and Jadon Sancho all received racist abuse on social media after missing penalties in the shoot-out defeat to Italy in the final of the last Euros.
