Wojceich Szczesny is confident that he will keep his place as Arsenal’s Premier League goalkeeper despite facing internal disciplinary action over smoking and being left out for the FA Cup win against Hull City.

Arsenal face Stoke City on Sunday and Szczesny, who has always started this season in the Premier League or Champions League whenever he has been fully fit, is understood to have been personally reassured that he is in the team this weekend.

Bizarrely, Szczesny was caught lighting a cigarette in the shower at St Mary’s after the 2-0 defeat at Southampton and is now facing a club fine from a furious Arsène Wenger.

Contrary to claims from former midfielder John Jensen, however, Wenger has not decided that Szczesny should be dropped as a result of the incident.

Szczesny’s place was in some doubt anyway following his errors in the Southampton defeat and the availability now of both David Ospina and Emiliano Martinez.

Wenger and Szczesny, however, have discussed the situation this week and the manager does not regard the incident as sufficiently serious to demand any sanction beyond a fine.

Although there have been other mistakes this season – Szczesny was sent off against Galatasaray in the Champions League – Wenger has been satisfied with most of his performances, particularly in last month’s 2-1 win against West Ham United.

Wenger has also always shown considerable faith in Szczesny since he arrived as a 16-year-old, first by promoting him when he could have signed Hugo Lloris in 2012 and then again last summer when he recruited Ospina as his understudy.

At 24, however, Szczesny is now approaching an age where he will be expected to deliver on his potential and show the benefit of all the experience he has gathered at such a young age.

He shared the ‘golden glove’ award for most Premier League clean sheets last season with Petr Cech and, although Wenger has scouted other goalkeepers, Szczesny will get further chances this season to prove he can become Arsenal's long-term number one.
