The Red Devils have endured a number of number of casualties this season with Angel di Maria the latest to be examined over a possible long-term layoff.
In defence especially, Van Gaal has bemoaned his inability to pick a settled back four, and has often relied on rookies Paddy McNair and Tyler Blackett to plug the gaps, as illustrated during United's recent victory over Hull City.
Likewise, the Gunners have also endured somewhat of an injury crisis as regular defenders Per Mertesacker, Mathieu Debuchy, Laurent Koscielny and Kieran Gibbs have all at some point spent time in the treatment room.
Hector Bellerin has been handed his first Premier League start in recent months, whereas Nacho Monreal has been deployed at centre-back prompting Wenger in recent days to demand credit for dealing with his unlucky situation
Mourinho, however, has refused to use injuries or suspensions as some sort of excuse as the Blues manager was asked on how he expects to deal with Diego Costa’s upcoming suspension.
“I was told he [Costa] was unlucky to get the yellow card,” he told Chelsea's official website. “We’ll play Remy or Drogba against Tottenham Hotspur. We don’t cry about injured or suspended players. He can rest and be fresh against Newcastle. It’s no problem, let’s go.”
While the Portuguese chief appears to take a slightly different stance on injuries, one can only wonder whether he would say such things if the Stamford Bridge outfit weren’t sitting pretty at the top of table.
Following their 0-0 draw at Sunderland, the Blues extended their unbeaten run to the start of the season, and it would take a brave man to bet against them from lifting the Premier League title next May.
