Chelsea head coach Mauricio Pochettino commented on his team's defeat in the Premier League match against Aston Villa on Matchday 6.
"I'm not disappointed - just sad. I think we were the better team before the red card. The team tried their best, and we can't give up. Playing with ten men is always difficult, but the team worked hard.
We need to change this situation. I know the only way to change it and that is to work really hard. We are confident in the way we want to play football. We just lack goals. If we keep working hard, we will change that," Pochettino told the BBC.
