De Gea could now be looking to join Real Madrid this summer and the Spaniard failed to end speculation at a recent media day, insisting that he is remaining fully focused on the World Cup in Russian Federation.
Reports emerged at the end of last week suggesting Real are primed to make their move for the Spaniard.
The newly appointed Prime Minister of Spain, Pedro Sánchez, visited the national team squad recently to wish them luck before they began they set off to Russian Federation for this summer's World Cup. It's very important to have a good World Cup and I hope we can go far and win - that would be incredible. Hopefully, we can go far and win.
"From the off I gave a press conference saying it was all a lie but people spoke about me", De Gea told Spanish sports newspaper Diario AS.
"I am a very calm guy and it is hard for me to be affected, but you have family, people close to you, who are affected more". Come what may, I'll be the same.
"It is important to be focused and be 100 per cent".
The allegations were later found to be false and De Gea and Atletic Bilbao midfielder Iker Muniain, the other player implicated in the scandal - were not called to provide evidence by the judge in the case.
The centre-back reportedly thinks it is time for the club to attempt the signing of a different goalkeeper - Atletico Madrid's Jan Oblak. Many who have criticised me, but then later knew that they were wrong, and have not given the face and rectified. It personally didn't affect me much but obviously I have people close to me that are affected by this more than me.
Spain completed their 2018 World Cup warm-up schedule with a 1-0 victory over Tunisia on Saturday, following on from a 1-1 draw with Switzerland at El Madrigal a week prior. "It's the same feeling of doing things well and helping the team, of becoming strong".
"We also have a great national team, and it will be a tough game". De Gea said he is ready to counter star Real marksman Cristiano Ronaldo.
