I'm not an expert in football, but it seems to me that young players who are eager to prove themselves should be given a chance (like Sychev and Arshavin did in their time, and now Dzagoev). When people receive astronomical salaries, they have no motivation. IMHO.
But it seems we are not seeing the hidden part of the iceberg; there are only guesses that a lot of money is circulating around football through betting, and politics are also involved, which leads to illogical lineups and unexpected results.
