Tottenham Hotspur defender Milos Veljkovic has warned his team-mates not to underestimate Partizan Belgrade when the two teams face each other on Thursday.
The youngster was in action with the Serbia Under-21 last week and explained that the Partizan players are determined to kick-off their European campaign in style.
"Nemanja [Petrovic] and Andrija [Zivkovic] are very good young players and I know they are very important to Partizan,
"I was speaking to them last week and they are looking forward to this game.
"Partizan is a great club in Serbia, they have a strong support and have been champions on many occasions.
"Partizan and Red Star Belgrade are especially strong at home.
"They are always in the Champions League and that shows their quality. It will be a big challenge for us.
"I go to Serbia every summer for the holidays and I’m looking forward to this one."
