Arsene Wenger has admitted that some players are never the same after serious injury and fears the psychological impact of Aaron Ramsey's broken leg.
The Arsenal midfielder sustained fractures to the tibia and fibula of his right leg following a challenge by Stoke's Ryan Shawcross at the Britannia Stadium last weekend.
He will now be sidelined for the foreseeable future but has vowed to return stronger than ever from the sickening blow.
Wenger has no doubts that he will make a full recovery physically but he is more worried about the mental trauma of such an experience.
"When you are a football manager you are always scared," said the Gunners boss.
"If you have a Ramsey injury, you know he will come back. But you never know what the psychological impact on your future game is and that is what you are scared of.
"Some players put their foot in straight away again and some players are never the same. They lose that little bit of freedom to go into the challenges.
"Lose just that and you are not the same player."
Wenger believes Arsenal can use Ramsey's injury as inspiration for their title charge after overcoming Stoke 3-1 to close to within three points of leaders Chelsea.
"The Ramsey incident gives us one more reason to do it," he explained.
"This kind of thing can improve solidarity and I believe that is what it did last week.
"It was a hard-fought victory because Stoke are a good team and have shown that before in beating Manchester City.
"For us, it was a vital victory and has put us in a good position for the rest of the season."
