This is the main problem of Manchester United this season, they can show a great game against Liverpool, but in matches with Bournemouth or Brentford their performance will be very unconvincing. Chelsea, by the way, can even overtake Manchester United on goal difference if they win two games, because they have played two matches less than Manchester United. But this is not so important, since this season can be considered a failure for Manchester United and Chelsea.
Manchester United and Chelsea are nothing different, when they face mediocre teams, they either lose or draw. When they meet strong teams, they able to give a fight and sometime they win.
Today we will see Liverpool vs Crystal Palace and Arsenal vs Aston Villa.
Seems to be like easy win for Liverpool and Arsenal, although the previous performance by Liverpool was really unexpected by a lot people.
