Former Manchester United midfielder Schweinsteiger revealed De Gea's "angry" reaction to Bayern Munich goalkeeper Neuer.
The German legend played for Old Trafford from 2015 to 2017, after he won 13 trophies in Bavaria, during which he played alongside De Gea when the Red Devils won the 2016 FA Cup under Louis van Gaal and the 2017 Europa League under Jose Mourinho.
Before Old Trafford played alongside De Gea, Schweinsteg had another outstanding international goalkeeper in his side – Bayern's Neuer. Since then, he has exposed De Gea's contempt for being told he was inferior to the German goalkeeper. Talking to people about BBC Radio Five live broadcast Schweinsteiger said: "When I first came to Manchester United, De Gea said, 'Tell me, am I better than Nuel?' ’

"I said 'no, you're not'. It's a different level. He was angry, but I explained why. Whenever he has a great game and he asks me again, I'll still say he's not up to that level. Schweinsteg pondered De Gea's mentality ahead of Liverpool's defeat on Sunday, when United were slaughtered 5-0 by rivals and Mohammed Salah poured salt on his wounds, becoming the first Premier League player to score a hat-trick at Old Trafford.
Ole Gunnar Solskjaer's current pressure has increased by 9 degrees. After that defeat, Ole Gunnar Solskjaer's position was almost untenable, and even before playing last Sunday, Schweinsteiger suggested that the Norwegian had "taken too long" to make progress at the club.
He added: "Manchester United are still in the works. Ole Gunnar Solskjaer keeps mentioning this. But for me, it took too much of my time. 'If you look at Manchester City or Chelsea and look at the impact Tochel has had on them, it's unbelievable. He knows what the players need to do and they have their own strategy and DNA. "There's more in their game." The experience of Cristiano Ronaldo and Rafael Varane will certainly help the team, but the question is how much they invest in the team's tactics. "I'm still not entirely sure if United will succeed." 'They have great names like Paulo Boga and Cristiano Ronaldo and I think Marcus Rashford will help them a lot in the future because he's already injured. It's not easy for them. 'But if you compare their football to chelsea, Manchester City, Liverpool and even other teams in Bayern Munich, they're at a different level now. 'Manchester United can always hurt you in a game and that's obvious to me, especially at Old Trafford. It was obvious to me, especially at Old Trafford. ”
