Arsene Wenger knows Arsenal have no margin for error when they attempt to revive their Premier League title challenge against West Bromwich Albion on Monday.

Manchester United's executive vice-chairman Ed Woodward is "desperate to land Neymar," while "Woodward's rival at City, Khaldoon Al Mubarak, is working just as hard to pull off the biggest transfer coup in history for Messi."

Olivier Giroud came off the bench to help give Arsenal a 2-0 win over Bayern Munich and keep alive their Champions League hopes.
