It was as if the midfielder had never been away as he covered every blade of grass in our 3-1 victory in the fourth round of the FA Cup at the Lane.
In fact, it was JJ's first match action since suffering an ankle fracture against Arsenal on December 2.
He capped it all with our second goal, gliding into the six-yard box to tuck away Aaron Lennon's cross on the volley.
"I was very happy with JJ coming back," said Martin. "After 10 minutes I turned around to Chrissie (Chris Hughton) and told him 'we've really missed JJ' and you saw that in the first half.
"He's a very good footballer and Southend couldn't cope with him in midfield with his strength, his stamina and his runs forward supporting play.
"Paul Stalteri also came back, he can always do a job and he proved that again."
Jermaine Jenas took just 10 minutes on his return to action against Southend to show Martin Jol what he's been missing in the last seven weeks.
