David de Gea admits he's excited by the changes at Manchester United since Jose Mourinho's appointment.
De Gea has been enthused both by the summer acquisitions and appointment of Mourinho, with the player so often linked to Real Madrid clearly excited by the season ahead at Old Trafford.
Asked if United are capable of challenging for the Premier League this term, De Gea told Press Association Sport: "Of course, of course.
"I think we signed top players, really good players. We are Manchester United and we want to fight for everything.
"I feel for the fans, for the club and the players (that something exciting is coming) - you feel like (it is) a new era.
"I think the club is really strong now. The players, we want to everything and hopefully we can do it."
De Gea was speaking at the launch of United's new adidas home kit in Shanghai, where the goalkeeper emerged onto the stage alongside Mourinho.
The former Chelsea boss has quickly made an impact since succeeding the divisive Louis van Gaal, with his winning mentality, organisation and bulging CV impressing the Spaniard.
"He is a strong character," said De Gea, United's player of the year for the last three seasons.
"He is a winner - he is one of the best managers in the world and we feel it. We are really comfortable with him.
"He is a strong character but he makes jokes. It is good for us to laugh and I think he is a really good manager."
