English League Cup semi-final, second leg: Veteran goalkeeper Mart Poom has completed a permanent move to Arsenal after proving his worth while on loan from Premiership strugglers Sunderland.
The Estonia international has won more than 100 caps for his country and has vast experience of English football, making more than 200 appearances for Derby and Sunderland during his career.
Poom has yet to play for the Arsenal first team, but has featured four times for the reserves this season and is included in the squad to face Wigan.
The length of Poom's contract has not been officially announced but it is believed to be a one-year deal.
Wenger will unleash Thierry Henry on Wigan as Arsenal seek to overturn a one-goal deficit and reach the final. Henry was rested for the first leg which Arsenal lost 1-0, but he will start at Highbury as Wenger seeks to take the game to Paul Jewell's side and cancel out their aggregate advantage as soon as possible.
Wenger has previously used the competition to give his crop of talented youngsters the chance to gain valuable first-team experience, but the manager's desire to reach the final has forced him to dispense with that policy.
Goalkeeper Jens Lehmann has been rested, but Wenger is boosted by the return of Robin van Persie from a broken toe. Wenger will also keep faith with the defence which failed to prevent James Beattie hitting the winner at Goodison Park on Saturday.
Captain Henry, who watched the first leg on television, believes home advantage will be the key against Jewell's men. The League Cup is the only trophy Arsenal have not lifted under Wenger's tenure and Henry has promised an attacking evening.
"I watched the Wigan game but we are only at half-time," said Henry. "Of course it would have been nice to have come back with a draw or a win, but now we have got them at home, we know exactly what we have to do."
New signing Reto Ziegler, signed on loan for the rest of the season from Tottenham yesterday, goes straight into the Wigan squad. Manager Jewell beat off interest from a number of clubs to snap up Ziegler after he recently returned to Spurs following a spell on loan with SV Hamburg.
Neil Mellor, who signed on loan last Thursday from Liverpool, is eligible, but David Thompson is not following his move from Blackburn last Thursday.
Jewell is without a number of injured players in captain Arjan de Zeeuw, Lee McCulloch, David Connolly, Emerson Thome, Ryan Taylor, Steve McMillan and Ryan Taylor.
