The Arsenal boss also insisted the Olympic football tournament is not a real competition and players should not be allowed to play in both the European Championship and London 2012 next summer. The Football Association opened the door yesterday for the possibility of England players at Euro 2012 potentially turning out for the Great Britain football team, if a schedule could be worked out between England manager Fabio Capello and newly-appointed Olympic head coach Stuart Pearce. That could potentially affect Arsenal's Jack Wilshere, Kieran Gibbs and Alex Oxlade-Chamberlain, as well as Theo Walcott. Aaron Ramsey is also likely to be involved in Great Britain's 18-man Olympic squad. Wenger said: "If you look at the organisation of the whole summer, it makes life impossible for the clubs and the players especially. "At some stage you have to decide how far you can go medically for the players to play so many games under so much pressure. "I would say there is already no real break because of the European Championship and the Olympic tournament for me is not a real football tournament, for me the Olympics is for track and field basically." Wenger insists players require at least four weeks' rest after tournaments and believes playing in both would be unworkable. He said: "The competition (Olympics) is after the European Championship. The Euros finish on July 1, we start the championship on August 15, we start pre-season training on July 4 or 5, that means we will not have the players after the Euros. "If we are losing them as well to the Olympic Games I think I will have to sign a licence to practise all over the summer because we will not have players. It cannot work. "The Olympics finish in mid-August, so imagine a player who has played the Euros and Olympic Games. You think you can use him after that? It's impossible. I don't know what people think when they organise these competitions." Wenger also believes there is no way the decision can be left to players and wants the FA, who on Thursday said they did not want to "lock ourselves in" to a hard and fast decision on the matter, to show leadership. Wenger said: "Personally I think that is a very bad idea because, if the players decide if they play or not, whatever decisions they make they could be found guilty towards the club or towards the federation or to their country. "The worst thing is to leave that decision to the players. The FA has to be a little bit responsible. "If I ask you now who won the Olympic Games 20 years ago, you would have problems to tell me. If I ask you who won the Euro Championship, you know better and the World Cup even better. "It is a tournament (the Olympics) that you want England to do well in, but we have to be sensible and not make silly decisions. I believe the federation and clubs have to sit together and analyse the situation for every single player." Arsenal play Stoke on Sunday at the Emirates stadium and Wenger will be without full-back Carl Jenkinson, who damaged his knee in the midweek win against Marseille. He will choose between Laurent Koscielny and Johan Djourou at right-back. Arsenal have won five of their last six matches in all competitions and Wenger believes they are slowly beginning to turn round their stuttering season. He said: "That is what we want to achieve. We feel we want to especially continue the quality of our game and the result will be the consequence of that. Let's focus on defending well again and playing our football. "We have played eight games, we have 30 games to go so we do not have to look too much at the other results. What is important is that we have a consistent focus and then we will come back." Wenger believes it is a game which will suit 6ft 6ins German defender Per Mertesacker. He said: "I brought him here for more than this type of game [Stoke] because I feel he is a good player. "He is a good organiser, he understands the game, he is an intelligent player and physically he is getting sharper and sharper in every game. "He had no real preparation for the season and now you can see that we look less nervous at the back and he contributes to that."
