However, Van Gaal might just have to do without De Gea for the big English Premier League game against Arsenal next weekend, after the in-form goalkeeper suffered a dislocated finger during a training session for Spain on Friday.
Van Gaal has relied on De Gea for the entire season so far, and if the goalkeeper does turn out to be unfit for the clash against Arsenal, it will be a massive blow, as the Spaniard was the one person who has been a consistent, top-quality performer in the Manchester United backline.
"Spain international goalkeeper David de Gea has been removed from the training on Friday after suffering a blunt trauma to the fifth finger of the right hand that caused him a dislocation," Sefutbol said in a statement.
"De Gea will be assessed by the Spanish FA doctors before taking a decision."
De Gea is expected to miss Spain's Euro 2016 qualifier against Belarus on Saturday, and Spanish reports claim he could also miss the match against Germany next week as well.
While the Manchester United defence will be put in further disarray in De Gea's possible absence, there is some good news for Van Gaal on the attacking front.
According to Colombia manager Jose Pekerman Falcao, who has missed the last few Premier League games due to an injury picked up in training, should be fit to face Arsenal. Falcao watched from the stands as Colombia topped USA 2-1 in an international friendly at Craven Cottage in London.
"There is no doubt he is in optimal condition," Pekerman, when asked about Falcao's fitness situation, was quoted as saying by the Daily Mail. "He's recovered very successfully.
"He has done everything perfectly. This is a small muscular injury, it is different to the knee injury before the World Cup.
"He's in a good condition and could be ready for Arsenal. He hasn't even started yet. He will be one of the best players Manchester United have had and will break a lot of records in England."
Falcao has not quite hit the heights in the Premier League yet, but if he can shake off his injury problems then the goals should flow considering he has been able to find the back of the net with unerring regularity in pretty much every club he has played for in Europe.
