Portugal coach Fernando Santos has come under pressure from local media and fans following recent disappointments - including a last-16 Euros exit last year. There is also talk of tension in the squad and worries among fans that the team is too focused on serving captain Ronaldo, who at 37 is past his prime. “The environment in the changing room is excellent. No problems, ” five-times Ballon D’Or winner Ronaldo said on Monday. “The group is shielded. And I take this opportunity to say: stop asking about me. ” But the chances of Ronaldo stepping out of the spotlight look slim in the wake of an explosive TV interview in which he said he had been betrayed by Manchester United, prompting speculation that he will soon leave the club.
