Arsène Wenger and the Club’s medical staff are leaving no stone unturned as they try to get to the bottom of Cesc Fabregas’ ongoing hamstring problem.

The Arsenal captain was forced off during the second half of Tuesday’s defeat in Braga with a recurrence of the injury that has dogged him for some time.

Fabregas’ hamstring has already kept him out of four of Arsenal’s 14 Premier League games this season and he is set to miss at least a couple more. Wenger’s concern is obvious and he wants answers.

“We have analysed his body and it is not fatigued and he is not tired,” explained the manager.

“He is a guy who just has a little bit of a hamstring problem but where does it come from? Does it come from his back, from the fact that he is naturally not flexible?

“We are investigating as much as we can. The problem [is] before when you were injured you waited at home and when you could play again you played again – today you can have ten scientists around you but you still get injured.

“We will consultant every specialist we can. But at the end of the day it doesn't stop him from being injured.”

Wenger admitted after the midweek defeat in Braga that he had “gambled” by fielding Fabregas from the start. But the Frenchman insists that he has not taken unnecessary risks with his captain’s fitness.

“When you’re 23 years old you want to play football when you are fit,” said Wenger.

“We had a chat before the game on Tuesday and he felt perfectly alright. All the data we had was positive so it’s difficult to say to a player ‘I know you’re fit, I know you feel good but you don’t play’.

“On the other hand if you look at the number of games Cesc played, you can see he played more games than last year and the year before.”

Fabregas’ importance to the Arsenal side is obvious and Wenger admits that the responsibility the Spaniard shoulders may have an indirect effect on his well-being.

“I think he has more pressure on his shoulders than before,” said the manager. “Pressure to do well, pressure to deliver, to be the captain. He feels responsibility to win things that’s for sure.

“I don’t know if that has an influence but it’s difficult because you can have psychological reasons or physical reasons – it’s difficult.”
