Arsenal goalkeeper Manuel Almunia admits he finds it difficult working with rival Jens Lehmann.

Lehmann has constantly been sniping at Almunia this season and the Spaniard told AS: "It is not easy to work every day with a person like this.

"If somebody wants to be bitter, it won't bring them closer to other teammates.

"The first year was not bad in the beginning, it was the other way around. It began to change that same season when Wenger gave me a few games. It is very difficult to explain that type of behavior, but I imagine that he thinks that this is the law of the jungle."
