Arsenal will face Ruud van Nistelrooy’s PSV Eindhoven in the Europa League group stages while Manchester United have been drawn with Spanish side Real Sociedad, Moldovan champions Sheriff and Cypriot minnows Omonia.
Former United striker Van Nistelrooy was involved in several high-tempered clashes with Arsenal during his playing career, notably with defender Martin Keown in 2003 when the rivalry between the Premier League sides was at its peak.
