Last night's draw with Bournemouth left Spurs in ninth place on the table.
"We have to win for ourselves and our fans. We want to be higher up the table and fight for a Europa League or Champions League place. It is a battle that we must take seriously and where we must do well," Winks said.
In Thursday's game, Harry Kane was denied a penalty call and Winks added: "I've seen the episode and I do not understand why we have VAR. There is a penalty kick. One could argue that we could have done better, but there was definitely a penalty kick."
