Arsenal forced to wait for Real Madrid striker Higuain
The Sun says the move has stalled because of Real Madrid's managerial merry-go-round.
The Argie striker, 25, is refusing to make any decisions on his future until a successor to Jose Mourinho is confirmed.
Paris Saint-Germain chief Carlo Ancelotti is the favourite for the job.
The Gunners are locked in a battle with Italian side Juventus for Higuain.
