(CNN)It's often said you can tell a lot about a man by the company he keeps. It's an aphorism worth remembering on arguably the most hectic day in the football calendar as clubs rush to grab a deal on transfer deadline day. And according to one football scout, a young man's friends can also tell you if he's going to make it big in the beautiful game. Lutz Pfannenstiel is a former player who now works for German club Hoffenheim, scouring the globe in the hope of finding a future star. Profiling players, and seeing how they behave off the pitch, is key to understanding whether they are right for the Bundesliga, insists Pfannenstiel -- who played for 25 clubs during a rich and varied career.
