text: Theo Walcott understands just how difficult it is now to hold down a place in the Arsenal side, who he says have been the 'best team in Europe' this year and could lift the title next season if everyone stays fit. The Gunners' slim hopes of overhauling Chelsea's 10-point lead at the top of the Barclays Premier League were all but extinguished following a goalless draw at the Emirates Stadium on Sunday. Walcott watched on from the bench again before a late substitute appearance, with the forward's last club start having been back in March. Theo Walcott believes Arsenal have been the 'best team in Europe' in the second half of the season . Arsenal had earned eight successive Premier League victories before the 0-0 draw against Chelsea . The 26-year-old - who recovered from a serious knee injury last season, but has yet to agree a new long-term deal - feels such strength in depth can only be positive for the squad, if sometimes frustrating for individuals. Fellow England internationals Danny Welbeck, Jack Wilshere and Kieran Gibbs also did not make the first XI against Chelsea. 'There is a lot of competition for places so everyone seems to lift a gear and play extremely well. It makes it a bit more difficult for people to get into the team,' Walcott said, quoted on the club's official website, www.arsenal.com. 'I think, especially this season, not many people thought we would be challenging for the Premier League. 'In this calendar year, we have been the best team in Europe. 'It is the strongest the squad has been and everyone is staying fit as well. The English midfielder (left) has struggled to maintain a first team place under Arsene Wenger this season . 'There aren't many injuries in the squad, which is important. If we had an injury-free season, I think we could lift the title.' Arsenal head to Hull on Bank Holiday Monday looking to keep pressure on Manchester City in the race for second place, and with it automatic qualification for next season's Champions League. Captain Mikel Arteta is set to step up his training this week after an ankle problem hampered recovery from a calf injury, while midfielder Alex Oxlade-Chamberlain is another continuing rehabilitation from an inflamed groin which has seen him out since the FA Cup win at Manchester United last month.
