Arsenal manager Arsene Wenger says he has no idea why his team has suffered so many injuries in the last five years.
Attacking midfielders Santi Cazorla and Alexis Sanchez have joined a long list of players who suffered long-term injuries during the last five seasons, a list that includes the likes of Jack Wilshere, Theo Walcott, Alex Oxlade-Chamberlain and former players Lukas Podolski and Bacary Sagna.
But the 66-year-old insists that the Gunners suffer the same amount of injuries suffered by other top clubs in Europe.
"I don't know," the Frenchman said.
"For example with these injuries you count Abou Diaby who was injured a lot here and has gone to Marseille and still does not play.
"I believe that is a debate that I will leave to specialists but… it is not difficult to compare our injuries across Europe with all the leagues and I don't think we have more injuries than everybody.
"I would like to invite you to see one day [how the medical team has changed in the last 20 years].
"We have plenty of people. When arrived here it was me, my two assistants and Gary Lewin, but today you have a team around you. That has changed and I think that has changed everywhere. It is much more sophisticated, much more scientific, but human beings are still human beings.
"We are quite sophisticated in testing our players. I had a chat with Alexis after his injury and he was adamant he felt perfect before the game because we tested his strength, stretching, all the signs we test every week were perfect.
"There was no obvious sign or alert before the game - it happened, do I have to take the blame? I do, but there was not an obvious mistake to select him before the game."
