Links with Chapman make it a special tie – Wenger

Almunia, 33, has not played since the end of September when he injured his elbow saving a penalty in the home defeat against West Bromwich and then suffered an ankle problem when he was close to a return.

In the Spaniard's absence, Lukasz Fabianski, who has since picked up a shoulder injury, and then Szczesny impressed when stepping in between the posts.

Almunia has had offers to leave during January, from both Spain and Turkey, but could yet stay and battle to win his place back.

"At the moment Wojciech is No 1," said Wenger. "He has done nothing for me to take him out, but I can rotate the goalkeepers."

Arsenal are expected to roll over the League One Terriers to carry on their momentum from the midweek Carling Cup semi-final win against Ipswich.

While Wenger will again rotate, with the likes of centre-back Sebastien Squillaci, midfielder Abou Diaby and winger Tomas Rosicky in contention, he has warned against any complacency.

"One thing with the fact we are involved in the four competitions is that we need a super-realistic approach and focus on the next game, just try to win it," he said.

"You build the confidence in the team slowly and you lose it very quickly. One big, bad result and you are down very quickly.

"So it is important to keep our feet on the ground and to show we have learned from Leeds and Ipswich how difficult these games are.

"We are on a good run and feel we have a good confidence level and a good attitude in the whole squad. We are getting stronger and stronger, so that is what we want to do."

The Gunners manager played down any suggestions of delivering the quadruple.

"What is good is that we are involved in all competitions and we are hungry to do as well as we can.

"What can we do? We don't know. But we are hungry and have the desire to do as well as we can."

With the return of Squillaci and Thomas Vermaelen expected to be back in around six weeks, Wenger believes there is enough cover in the centre of defence, but will still look to bring in a "special player" if one emerges.

Former Arsenal manager Herbert Chapman, who helped transform the club in the 1930s, guided Town to consecutive league titles in 1924 and 1925 and they went on to win a third straight crown without him in 1926 as he left for London.

Wenger is in no doubt what the Arsenal of today owe the innovator, who introduced floodlights, the use of physiotherapists, shirt numbers as well as the famous 'WM' 3-2-2-3 formation.

"We are a modern club, but have a big respect for tradition," said the French coach, who has transformed the club's fortunes over 13 seasons.

"This cup tie has a special meaning because Chapman was the most influential manager at this club and so we have big respect for that.

"Chapman was a super pioneer because he really turned this club into the modern era. He was ahead of his time and he was certainly the most influential manager."
