Arsene Wenger confident Robin van Persie will keep scoring

Arsenal boss Arsene Wenger is confident that contract negotiations will not affect Robin van Persie's outstanding form, as his team prepares for Tuesday's Champions League match-up with French side Marseille.

Van Persie took his tally to 28 goals in 27 Premier League games with a hat-trick in the weekend's 5-3 defeat of Chelsea.
