Wenger's wait!: Arsenal beaten by Birmingham in Cup final

WEMBLEY, England (AP):

Birmingham won their first trophy in 48 years after a mix-up between Arsenal goalkeeper Wojciech Szczesny and defender Laurent Koscielny allowed Obafemi Martins to score an 89th-minute goal to clinch a 2-1 victory in the League Cup final yesterday.

Szczesny and Koscielny went for the same ball from Nikola Zigic's long pass into the box. The ball landed at the feet of Martins, who slid it into the net six minutes after coming on to the pitch.

"I think it was my second touch," said Martins, who joined Birmingham on a six-month loan from Rubin Kazan last month. "I think this is the easiest goal I've ever scored in my career - and it's very important."

Birmingham, the 1963 League Cup winners who are sitting only two points above the Premier League relegation zone, overcame a side second in the standings at Wembley Stadium.

"A little misunderstanding had great consequences for the result," said Arsenal manager Arsene Wenger, whose team hasn't won a title since the 2005 FA Cup. "It was a lack of communication and lack of determination as well because always when a ball is in no man's land someone has to take responsibility and go for it really."

"For a small club like Birmingham to beat the might of Arsenal is a dream come true," Birmingham manager Alex McLeish said. "We weren't given a prayer by the pundits and the bookies but we believed today. It was a titanic performance by the players."

Three finals have been lost by Arsenal since 2005 as Wenger's wait continues for his youthful side to have something to show for its eye-catching football.

That lack of success, Wenger conceded before the match, had placed "a weight on the team." Only this season has Wenger selected strong sides in the League Cup, which he had derided in previous years and fielded young players.

Wenger hoped the final would show how far his side has matured, but Arsenal were sluggish and struggled to impose themselves.

The Gunners looked nervy as passes went astray and had failed to heed the warning of Fabregas before the match that you are likely to lose when contesting the ball in the air with Zigic.

Corner goal

That transpired from a corner after Arsenal right back Bacary Sagna had conceded possession. Birmingham defender Roger Johnson soared above Koscielny to meet former Arsenal winger Sebastian Larsson's corner and nodded goalward to Zigic.

The Serbia striker - the Premier League's tallest player at 2.03 metres (6-foot-8 inches) - found space among five Arsenal players to head beyond Szczesny.

The equaliser came after Jack Wilshere hit the crossbar from the edge of the edge of the penalty area and the rebound was only partially cleared by Barry Ferguson's header. The ball fell to Andrey Arshavin on the right flank and his cross was volleyed home by Van Persie.

While Wenger was left ruing yet another blunder from one of his goalkeepers - at the root of many losses in recent years - in Birmingham's Ben Foster he saw an assured 'keeper'.

Foster, who won the League Cup with Manchester United in a penalty shoot-out in 2009, denied Arshavin with his legs in the opening minutes and thwarted Samir Nasri twice and Bendtner toward the end of the match.

While Birmingham has qualified for the Europa League with the win, the priority is staying in the Premier League.

Arsenal will turn their attention to an FA Cup fifth-round replay against Leyton Orient on Tuesday and a Champions League last-16 match against Barcelona the following week.
