BBC Match of the Day commentator
"Jurgen Klopp and Arsene Wenger are from cities just 66 miles apart across the French-German border, and have formed a mutual admiration over six Champions League games between Arsenal and Borussia Dortmund.
"For now though, the niceties end - with Liverpool v Arsenal games always having an edge.
"Klopp's Reds are battling gamely with brutal January fixture and injury lists, and much of their hopes here rest on what central defensive pairing he can field.
"The Gunners have coped with their own injury worries superbly, winning seven of their last eight games in all competitions.
"No Francis Coquelin, no Santi Cazorla, no Alexis Sanchez - no problem...a trip to Southampton aside."
