Manchester United goalkeeper David de Gea admits the Chinese weather is a test for the players.
The extreme heat and humidity has not stopped Mourinho’s men from often training twice a day in sweltering Shanghai, where on Friday they lost 4-1 to a Borussia Dortmund side admittedly far more advanced in their pre-season preparations.
“With the heat, with the humidity, it is really tough but we enjoy China,” said De Gea, who watched the International Champions Cup loss from the sidelines.
“It is my first time here. It is really hard training but we enjoy it a lot.
“It is unbelievable the fans in China. It is really crazy, but it is good for us. We enjoy it a lot.
“Of course (the tour brings us closer together), with a new manager and with new players.
“Of course we need to train, train and try to be a compact team.
“The key in pre-season is try to be fit as soon as possible and then go to the Premier League and try to win.”
