Former Arsenal goalkeeper Jens Lehmann believes that Mesut Ozil can fire Arsene Wenger's side to a Premier League and Champions League double this season.
The German playmaker became the club's most expensive player when he arrived from Real Madrid for £42m and he has been instrumental in the north London club making a wonderful start to the new campaign.
Arsenal are three points clear of Liverpool at the top of the Premier League table and look set to qualify for the knockout stages of the Champions League after securing a memorable 1-0 victory over Borussia Dortmund in Germany.
It has been some nine years since Arsenal last won the league title but there is a new found belief around the Emirates that this barren run will come to an end this season.
And Lehmann, who was a member of the Arsenal squad when they won the league in 2004, believes that Ozil could prove the catalyst for success both domestically and in Europe.
When quizzed on whether he thought his former club could win the Champions League, he told Talksport: "Of course. They have a chance to win everything.
"It's always good to lead the league and with Ozil they have a very technically gifted player.
"I hope he will add something to the squad in big games and they can go all the way to the Champions League final in Lisbon and win the Premier League title."
Arsenal face a big test of their credentials this weekend as they look to bounce back from defeat to Manchester United by defeating high-flying Southampton at the Emirates this weekend.
Victory over Southampton will certainly not come easily as Mauricio Pochettino's side have lost just one game all season and have already defeated Liverpool at Anfield and secured a draw with Manchester United at Old Trafford.
