Crystal Palace manager Ian Holloway says the world will now find out what type of club Cardiff City are, following their shock 2-1 home defeat to struggling Peterborough.

Talking ahead of Palace’s Boxing Day Championship clash at Cardiff, Holloway believes the Bluebirds’ 100 per cent record at New Cardiff City stadium was always going to end, but how they react will be revealing.

And after his own players threw away three points at Birmingham, Holloway, pictured below, says they need to get used to being 2-0 ahead.

Two goals from the prolific Glenn Murray, taking his tally to 20, had the Eagles soaring at Birmingham, only for Nikola Zigic and Papa Bouba Diop to drag them back to earth and make their point.

“Cardiff now know they are not invincible at home,” Holloway said. “It is not a surpise to me that Peterborough beat them, and I doubt it was a surprise to Malky [Mackay]. It is a sign of the strength of this league.

“But how the Cardiff players react is important, will they pick up their home game again against us or is it a chink in their armour?”

At St Andrews, Palace were without their suspended and influential skipper Mile Jedinak, and Holloway believes the Australian’s absence was signigicant in the final moments.

“There was a drop in concentration at Birmingham. We did not need to concede the corner that led to the second goal, and we could have done better defending the header.

“Had Mile been in the team, things may have been different because he is the one who  can organise the team.”

He added: “It is a little disappointing, but we have to remember this Championship race is not over until May and we need to keep going until then.

“If you look at the Olympics, how many of the athletes stopped half-way through their race? They keep going to until the cross the tape.”

Holloway says he has a fully fit squad for the weekend.
