Tunisia boss Nabil Maaloul has admitted that his side have "no choice" but to win against Belgium on Saturday.
Maaloul's team, who sit third in Group G on goal difference following their 2-1 defeat to England on Monday evening, face a Red Devils side in their second game who scored three against Panama.
The Tunisia boss told the Daily Mail that he will opt for a more attacking style of play to try to unlock the Belgian defence.
"We have to win. We have no choice," Maaloul said. "Belgium are very strong but we are ready. We want to avoid the mistakes we made in the first match.
"We will change our style. Our side is capable of unlocking their defensive line. What we want is to get to the back of the Belgian line and do that quickly.
"But Tunisia have weapons that I will not reveal. We have attacking skills and we will prove them tomorrow."
Should Tunisia lose against Roberto Martinez's side, and England beat Panama on Sunday, Maaloul's team will be eliminated.
