Laurent Koscielny has revealed he will require daily treatment on an Achilles injury for the rest of his career.

The 31-year-old was diagnosed with chronic tendinitis in both feet by the French Football Federation during an international break in October 2014.

Koscielny missed eight games at the time before returning to action and although he has featured regularly thereafter – making at least 38 appearances per season – the centre-back has suffered several Achilles problems since.

The latest occasion came just last month when he limped off at half-time of Arsenal’s 2-2 draw against Manchester City. He was subsequently sidelined for two games.

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.

And after consulting with medical staff at Arsenal in recent seasons, Koscielny has come to terms with the knowledge his Achilles condition will require close management until the day he retires.

“I have some problems,” he said. “Now it is better. I know it is a difficult injury because you need to work every day on this. Every morning I have my treatment for my Achilles and I know I need to do this to the end of my career.

“Now, every day I do this and it is OK but sometimes with all the games we play every three days, it is difficult and I need to have a rest to recover well for my Achilles. That’s why last time I was injured but now it is OK with this.

“It is not difficult 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. I know now I need to do this every day to be fit for my team.

“I am prepared to miss Sunderland to be fit for the last two games of this season. Sometimes it is better to miss one game to be fit for the others.”

The Gunners must win their final two League matches and hope either Manchester City or Liverpool drop points to ensure Arsenal do not miss out on a top four finish for the first time since Wenger took charge.

Fans are being urged to boycott this evening’s match in protest at the prospect of Arsene Wenger extending his 21-year stay at the club beyond the end of the season. There are expected to be at least 10,000 empty seats and Koscielny admitted the uncertainty over the manager’s future has affected some of his team-mates.

“It is a difficult situation, we don't know what happens with the boss,” he said. “But we are professional, we are salaried to this club and we just want to have the best result for this club – not to think about other situations or this situation of the boss.

“We are all in the same boat and the captain is Arsenal. We need to fight for this club and don't think about what is happening with the boss or the players. This is a situation, maybe some players don't feel great, but you need to be focused on our job and have the best results for Arsenal.”

The Gunners are expected to confirm their first summer signing in the coming days – offering the clearest indication yet that Wenger will stay on next term – after Schalke left-back Sead Kolasinac agreed a five-year contract to join on a free transfer.

The 23-year-old is set to switch clubs when his current deal with the Bundesliga side expires on July 1 and Koscielny believes the move is an indication Arsenal will still be able to attract top players even if they fail to qualify for the Champions League next season.

“I think that they know the players they want,” he added. “They know for a long time so I think if we are qualified or not for the Champions League they have targets in their head and they will do everything to have the best players for us, a player who can help the team to be better and who can change the team to have some more positive results for this club. Would Kolasinac do that? I hope!”
