"Bolton will not be an easy game because they know we had a tough match on Wednesday.
"We have to focus on it being difficult and our concentration will be the key. I hope we don't need an alarm bell to before we start playing well."
Hiddink is likely to make minor adjustments to the side for the visit of Bolton but will resist the temptation to rest a players.
"You must always be careful with temptations, professionally, and I think we still have to focus on the league," said Hiddink.
