I watched Casemiro and Manchester United make three unforgivable errors in Crystal Palace collapse

Manchester United were thrashed 4-0 at Crystal Palace on Monday as they sunk to a new low at Selhurst Park.

Erik ten Hag's side have now suffered a club record 13 defeats in the Premier League and are on course to miss out on Europe for the first time in a decade. United could still qualify for the Europa League via winning the FA Cup, but their chances of beating Manchester City at Wembley appear remote.

At least three of the Palace goals were preventable and down to sloppy defending from United who were chasing shadows throughout a torturous 90 minutes. Next for Ten Hag's team is league leaders Arsenal at Old Trafford on Sunday.

Below is a look at some of the key points from Modnay's horror show in South London...

Casemiro's irreversible decline

It is hard to see any way back for Casemiro at United. The Brazilian was superb last season but his decline in 2023/24 looks irreversible as injuries and age appear to have caught up with the Brazilian.

The Palace forwards had a field day at Selhurst Park with Casemiro looking shellshocked. It will be best for United to move the defensive midfielder on in the summer with the 32-year-old likely to cost United more points in the future.

Kobbie Mainoo's sloppiness

The young star was partly at fault for Michael Olise's goal with some lacklustre defending in midfield. It is a concern that the teenager has become sloppy in recent weeks as all momentum in United's season evaporates.

Are there now doubts over Mainoo's participation at this summer's European Championships with England? The 19-year-old has probably done enough to be included in Gareth Southgate's squad but he must regain his sharpness fast.

Mount fails Fernandes audition

With Bruno Fernandes missing his first-ever United game through injury, it was up to Mason Mount to provide some form of creativity in midfield.

But the former Chelsea playmaker looks off the pace amid an injury-hit campaign. It remains perplexing as to why United forked out £60million for the 25-year-old.
