The Red Devils currently find themselves well off the pace in the race for Champions League qualification this season, with Manchester United having only managed to win four of their opening 13 Premier League games.
Manchester United were pegged back and held to a 3-3 draw by Sheffield United at Bramall Lane last weekend as they dropped yet more important points in the Premier League.
Ole Gunnar Solskjaer has found himself under fresh pressure in recent days after the 2-1 loss to Astana in the Europa League on Thursday night.
De Gea insists that the mentality in the Manchester United squad is strong, but has hinted that he feels that the Red Devils may be lacking in talent in certain positions.
Speaking in an interview with Sky Sports, De Gea said: “The team is what it is, and results are what they have been recently.
“It’s true that the first half [against Sheffield United] was horrible, probably one of the worst this year.
“The reaction of the team in the second half was important, but it’s not enough. We should win these type of games to be on top, we need to win four or five games in a row to be at the top, but at the moment the team is not playing so well.
“We’re giving it everything, we’re trying to get those big wins that can put us high up in the table, but the truth is at the moment we’re not consistent enough, there’s much to train and much to improve.
“I don’t think it’s through any lack of effort, the boys are leaving everything out on the field in training and games. You could point maybe to a lack of quality in certain areas, but certainly not a lack of fight.”
Manchester United are currently preparing for their home Premier League clash against Aston Villa on Sunday afternoon.
They will then switch their focus towards their crunch showdown with Tottenham Hotspur at Old Trafford on Wednesday night in the Premier League, as Jose Mourinho prepares for a return to the Old Trafford dugout.
