Arsenal boss Arsene Wenger claims Jens Lehmann can help to get the best out of Manuel Almunia, and insists the pair share "a lot of respect".
Veteran German Lehmann, 41, has made a sensational return to his old club to aid the Gunners' injury crisis which has seen keepers Lukasz Fabianski, Wojciech Szczesny and Vito Mannone all sidelined.
The short-term deal, which is expected to be completed in time for Lehmann to take his place on the bench at West Brom on Saturday, will see the free agent sign on until the end of the season.
At the height of the acrimony between the two, Almunia went as far as claiming: "To have someone here who hates me is just amazing. I know he hates me."
