Criticisms of Jol include his tactics and substitutions, and his decision to take off Defoe against Middlesbrough put him in the spotlight, although his change was vindicated as Spurs turned the Carling Cup tie immediately after the switch.
Defoe has been left out of the matchday squad for the last two Premier League games and was upset at being taken off.
"He wasn't happy but Keane wasn't happy against Fulham," Jol said. "(Dimitar) Berbatov wasn't happy against Sunderland. It's the same all the time. Jermain did okay (against Boro) but not more than that."
Defoe's contract runs out at the end of next season and chairman Levy wants to avoid the England striker leaving for nothing like Sol Campbell.
"Of course," was Jol's response when asked if he wanted Defoe to commit.
