How do Atletico Madrid do it?
As soon as one star striker leaves, another comes up to take the role.
After Radamel Falcao left, Diego Costa filled his boots.
Arsenal, on the other hand, are still looking for a replacement for Robin van Persie who famously left for Manchester United in the summer of 2012.
Olivier Giroud is doing a fine job but he can't play every game for the Gunners and Nicklas Bendtner is in no shape to lead the line.
Arsenal have been linked with a mega money move for Costa and South American star will plug a gaping hole in Arsene Wenger's side.
