As shared by Squawka News, the Dutchman didn't hold back following the disappointing loss:
United put together another poor showing on Saturday, hardly ever threatening goalkeeper Fraser Forster's net as Southampton's defence easily handled the Red Devils' attack. The visitors didn't produce many chances, but substitute Charlie Austin found himself in the right place at the right time to hand his team the win just before the final whistle.
Fans and pundits alike questioned whether Van Gaal could stay on as manager following the loss, and the Times' James Ducker doesn't know what's next for the former Bayern Munich boss:
Per Kevin Palmer of the Sunday World, Van Gaal urged the fans to get behind the club and pointed at the numerous injuries that have set the squad back:
His analysis of the match was rather basic, per the Premier League's official Twitter account:
As reported by Jamie Allen of the club's official website, Van Gaal elaborated:
I think it was a poor performance - two teams who are not creating any chances and the lucky one has won. I had the fear already in advance with every change I did as we became weaker in the defence because [Marouane] Fellaini is a tall guy, [Matteo] Darmian is also a defender and he was out. I had the fear but we don't have to make that kind of foul, I think, and I changed [Cameron] Borthwick-Jackson for more of an attacker because I want to win this kind of even game, even when you are playing poorly.
His team appeared to play without any sense of joy and a severe lack of confidence, something he also addressed:
I can only say what I have seen. I think that, after a row of three victories and a draw in 2016, then you have a lot of confidence. That I didn't see today. Also, the expectations are very high and the pressure for the players is also high because of that. Of course, at half-time, I changed Juan Mata and saw, in the first 15 minutes, we were better and the fans were behind the team and cheering for the team. Darmian was injured and then it was gone. It's a pity we didn't continue with our momentum.
There were even more injury concerns for the Red Devils on Saturday, as star full-back and summer signing Matteo Darmian left the pitch after a clash of heads with Shane Long.
Per the club's official Twitter account, Van Gaal confirmed the Italian went to the hospital:
The Dutchman's fate seems to hang by a thread following the loss, and with an FA Cup clash against Derby County on the schedule, another poor performance could well signal the end of his tenure.
