The Bluebirds lost 1-0 at Fulham today to leave them perilously close to relegation to the Championship.
Cardiff’s safety relies on whether Brighton can pull themselves clear of the drop in the next couple of games.
However, despite being down the wrong end of the table, Neil Warnock’s side have managed to keep nine clean sheets this term.
And incredibly, that is more than both Arsenal and Manchester United have recorded all season.
The Gunners, who failed to keep a clean sheet away from the Emirates until earlier this month, have eight to their name.
While David de Gea’s United have only managed seven since the beginning of the campaign.
Bernd Leno joined Arsenal in the summer, replacing Petr Cech as the club’s No 1.
But Unai Emery has not been able to sort the Gunners’ historically leaky defence.
Meanwhile, over at Old Trafford, the same problems exist.
Jose Mourinho was desperate to land a new central defender in the summer but failed to strengthen United’s backline before his departure.
Ole Gunnar Solskjaer temporarily stopped the rot but has since seen his side’s form drop off in recent weeks.
As for Cardiff, the Welsh outfit are in serious danger of relegation.
Speaking after their narrow 1-0 defeat today, shot-stopper Neil Etheridge said: “We had our chances. It is a tough one to take. Both teams were tentative and we came out on the wrong end of it.
“We stayed in the game throughout. A fantastic strike broke the deadlock, we had our chances but could not take them.
“We felt we had to get something from the game, we haven’t. It was never in our hands. Hopefully Newcastle do us a favour and we are in it at the end.”
