Players wore the new strip – a white shirt with large red cross on it – in a Champions League match last month against Turkish team Fenerbahçe to celebrate the club’s centenary.



But a Turkish lawyer, Baris Kaska, took exception to the "Crusader-style" cross which he said symbolised "Western racist superiority over Islam".



He claimed the offending shirt reminded Turks of an emblem of the Christian order of the Knights Templar.



Mr Kaska, who specialises in European law, has lodged a complaint in a local court against the club.
