Wenger fell over while carrying bags into Liverpool's Lime Street Station after the loss, needing help from police to get back on his feet.
Meanwhile, the Reds celebrated their three points in smart fashion, with Daniel Sturridge posting a dressing room snap on Twitter.
"Teamwork make the dreamwork!! #ds15 #redordead #ynwa," said Sturridge.
Sturridge scored Liverpool's fourth during an explosive start that saw four goals for the hosts inside the first 20 minutes.
