Borussia Dortmund defender Neven Subotic is confident his side\'s recent successes are not going to the heads of the players. The Westphalians have won back-to-back league titles and also won the DFB-Pokal last season, but the Serbia international insists he and his team-mates are keeping their feet firmly on the ground. \"What we have managed very well so far is not to have any divas in the team and I cannot see why that would change,\" he said. Dortmund have broken with recent tradition by spending heavily this summer, with Marco Reus arriving for a fee reported to be in excess of €17m from Borussia Monchengladbach, but Subotic expects him to settle in like any other member of the squad. \"He is a humble guy,\" he told Kicker magazine. \"The only way anything can change would be if one player\'s character left them open to being attacked. But all the lads here who have signed new contracts deserve them and I know how hard they have worked for them.\"Subotic: No divas at Dortmund
