Mark McGhee believes his Motherwell are capable of shocking the Old Firm after yesterday's victory over Hibs.
The Fir Park side ended Hibernian's unbeaten Clydesdale Bank Premier League run as Ross McCormack struck twice in three first-half minutes against the 10-man visitors.
The result prevented John Collins' team going to the top of the table.
And McGhee, who named an unchanged side for the fourth successive match, will take his team to champions Celtic next Saturday in high spirits before they host Rangers in the CIS Insurance Cup quarter-finals the following Wednesday.
He said: "With the team we have and that little bit of help on the bench, we have a chance of beating anybody in this league given the way we're playing.
"We could beat anyone on a good day - maybe even the Old Firm, who knows?
"It's a big ask to keep that going until the end of the season, but as long as that team's playing, we have a chance of winning games.
He also insisted the best is yet to come from McCormack, after the Scotland Under-21 player netted a wonder strike and a free-kick to cancel out Steven Fletcher's penalty opener.
The striker also scored a spectacular goal last month as Motherwell dumped holders Hibs out of the CIS Insurance Cup with a magnificent 4-2 win at Easter Road.
McGhee said: "You saw a top performance from Ross today and his general play was good, but he could still play better.
"His goals certainly were top quality - his first certainly was fantastic and he's been practising free-kicks during the week which paid off for him with the second.
"They were two great goals and we fought back well; we lost [the first] goal in the cup tie as well, so maybe that helped as the players knew they'd come back from that at Easter Road as well.
"I felt we might get another goal but there was always a risk that we lost two points as long as it was 2-1, as they hit the bar near the end."
