Serbia defender Aleksandar Lukovic insisted Wednesday his side will back to their defensive best for Sunday’s World Cup clash against Ghana despite having leaked three goals last time out.

Serbia came from behind twice last Saturday to seal a 4-3 win over Cameroon in Belgrade in a friendly, but Udinese left-back Lukovic said the White Eagles will be much tighter at the back for their opening game.

“We didn’t lose any confidence against Cameroon, our defence remains one of the strongest parts of our game,” said Lukovic with Manchester United’s Nemanja Vidic and Chelsea’s Branislav Ivanovic set to lead the Serb defence.

“All of the team works hard in defence, we were maybe a bit naive in conceding three goals to Cameroon, but it was only a farewell match before we went to the World Cup.

“I truly believe everything will be fine for our first game against Ghana.”
