Arsenal are eyeing up a move for Borussia Dortmund star Marco Reus to replace Theo Walcott. The England winger risked irking Arsene Wenger by claiming talks over a new deal have not started, despite the Gunners boss repeatedly stating the opposite. Wenger confirmed the club's intention to offer Walcott a new contract in February and when asked about whether talks had started on March 13, the Gunners boss replied: 'The first contacts have been made and we will see how that progresses.' However, Walcott, who currently earns £90,000-per-week, took to Twitter  to contradict his manager.
