Chelsea boss Guus Hiddink won't seek excuses should they fail against Champions League opponents Juventus tonight.
He said: "I should have two, three or four weeks to observe the team and everything, and then I'd start working.
"But there's no time. That's not an aspect of top-level sport, to offer excuses. It has to be done in the moment against Villa and what we have now, home and away, against Juventus.
"Every manager would like four, five or six weeks to implement a lot of things. But I have to do that in a reduced time, a pressured time. But we have to do it.
"I'd like to underline, we must not give ourselves an excuse because, if we do, there's a tendency that we go a little bit less and that's not good in the boys' minds."
