Arsenal striker Emmanuel Adebayor has questioned his side's ability to win the Premier League, unless they start to develop a winning mentality.The Gunners appeared to be heading for victory over arch-rivals Tottenham on Wednesday, but conceded two late goals to draw the game 4-4.The 24-year-old suggested his team-mates thought the game was won and was at a loss to describe what went wrong."To be champions in this way? You can never be a champion," Adebayor said.Arsenal manager Arsene Wenger was furious at his side's capitulation at the Emirates Stadium and Adebayor echoed his manager's sentiments.The Togo international added: "There is a lot of disappointment. We are down at the moment because we did everything to get the three points and we ended up with one."We feel very sorry for ourselves that the things are not going the right way."It was one of the most difficult games in my life because I cannot understand that after 90 minutes we were leading 4-2 - I don't know how we finished with a draw."It's very easy to give up because we were 4-2 up and maybe thinking the game was finished. With five, six or seven minutes to go, maybe in our head the game was over."Going into this weekend's game away at Stoke, Arsenal are six points behind leaders Liverpool and have drawn two and lost two of their opening 10 games so far this season.They had also looked in control against Hull earlier in the season, but after taking a second half lead they failed to close out the game and goals from Geovanni and Daniel Cousin secured a memorable win for the Premier League new boys.That followed defeat away at Fulham in August, while last season their title challenge fell apart after Birmingham secured a late draw at St Andrews.Source: BBC
