Bayern Munich chief executive Karl-Heinz Rummenigge has slammed Robert Lewandowski after the striker questioned why the German champions didn't match the summer spending of Paris Saint-Germain and Barcelona. Lewandowski was clearly underwhelmed by Bayern's restrained spending, which saw them buy Corentina Tolisso from Lyon for £37.3million, Niklas Sule from Hoffenheim for £17.4m and make permanent the loan of Kingsley Coman from Juventus for £19.1m. They also took James Rodriguez on loan from Real Madrid and added other players such as Sebastian Rudy for nothing. It led to Lewandowski telling German magazine Der Spiegel: 'Bayern has to come up with something new and creative, if the club wants to keep luring world class players to Munich. 'And if you want to keep up at the very highest level, you need these players' quality.' But Rummenigge took the 29-year-old striker, who struggled in Bayern's surprise 2-0 Bundesliga loss at Hoffenheim on Saturday, to task over his comments.
