Ipswich Town 1 Arsenal 0: Arsenal manager Arsene Wenger refused to blame his defence after the shock Carling Cup defeat at Ipswich.
The npower Championship side will take a deserved lead into the semi-final second leg at the Emirates later this month after lone striker Tamas Priskin capped a fine performance with the only goal 12 minutes from time.
Priskin gave centre-halves Johan Djourou and Laurent Koscielny a torrid evening and should have opened the scoring before he did.
Wenger has been linked with a move for former Gunner Matt Upson at West Ham but refused to comment on the move.
However, with a Champions League tie with Barcelona on the horizon and the Barclays Premier League run-in looming nearer, Wenger's back four looks dangerously light of cover.
He said: “Let's not think that we lost the game because we haven't bought a central defender.
“We lost the game because we didn't play as well as we can.
“We have only two central defenders and we are short but I do not want to speak about any particular name.
“Frankly I am just disappointed about our defeat tonight. It is early to talk about a player coming in.
“We have nine games in January and it happens sometimes that you don't always play well in every game.
“As a team we did not have the performance we wanted.
“We were below our usual level in every department and it would be unfair to put the blame in the defence.
“When you play in one half the long ball has 50 yards to be dangerous.”
Ipswich caretaker manager Ian McParland had mixed emotions after signing off with a famous win.
McParland was in charge until Paul Jewell officially starts work this morning but is leaving the club as the former Wigan man brings in his own backroom staff.
McParland had just three days to recover after they were hammered 7-0 at Chelsea on Sunday and masterminded a performance of hunger and intense discipline.
He said: “They sweated blood. They were fantastic and it showed a lot of character to bounce back from Sunday's game.
“I knew that they were up for it.
“I said to them just stay in the game and keep it 0-0 as long as we could and we can always nick it.
“I'm leaving but I'll dust myself down and get on with it. I've been in football a long time, Paul Jewell is an honest lad, I've known him a long time and he will do well here now.
“I won't be going to the second leg. Hopefully I will have a job by then.”
Jewell was unveiled to the Ipswich crowd before the game but ensured all the credit went to McParland and the players.
