Don't tell me why the united was able losing with huge scores against sevilla this day. Look at MU's line up in defensive lines. All of players are just useless defenders. Lindelof, Meguire, Dalot and Bissaka. These are completed useless defenders. 

A bit surprised to see the line up that used by united before the match was just starting. It's also the reason why MU was losing against sevilla. All of players who very often made blunders are playing together.

So the defenders have made many mistakes. The gea is the only one who is pure defended its goal net from sevilla. MU has no defenders. De gea was only one.
