'That's why last time I was injured but now it is okay with this.
"Every morning I have my treatment for my Achilles and I know I need to do this to the end of my career".
The 31-year-old is now managing his game time due to a minor calf problem and will miss the Premier League visit of relegated Sunderland on Tuesday night.
"Now, every day I do this and it is okay but sometimes with all the games we play every three days, it is hard".
"It is not hard but you need to be careful with this because if you stop doing your own exercise programme for one or two weeks, the problem will come back", Koscielny added.
"You need to be careful with this because if you stop doing your own exercise programme for one or two weeks, the problem will come back".
Koscielny will not risk participation in Tuesday's Premier League match against Sunderland due to tightness in his right calf, principally with a view to ensuring readiness for Sunday's clash against Everton and the FA Cup Final six days later.
Arsenal are now monitoring his game-time carefully, especially with the FA Cup Final on the horizon, having made 42 appearances in all competitions this season. Koscielny is no doubt the first defender on the team sheet when fully fit and he's earned himself a high status at Arsenal.
The Frenchman had guided Arsenal into the Champions League in the last 18 seasons but looks set to come up short this time around. Then of course we have a FA Cup final to "look forward" to against the newly crowned Premier League champions. Lukaku is always a tough striker to play against and he troubles defenders so easily.
Koscielny was signed by Wenger from Lorient in 2010 and has developed into a key player at the Emirates Stadium.
'I may want to return to France but lots of questions would be asked because it's never simple being at a club like Arsenal for seven years and returning to France.
"It will be life choices, outside of football, that decide what happens next in my career", said Marseille coach Rudi Garcia. We need to fight for this club and don't think about what is happening with the boss or the players. "He did an unbelievable job so we need to respect this and his decision at the end of the season".
