New Arsenal signing Alexis Sanchez will be wearing the number 17 shirt, Red London understands.
The Chile international completed his move to the Emirates stadium on Thursday following a solid contribution for his country who bowed out of the World Cup only on penalties against Brazil.
Speculation had suggested that Sanchez would swap numbers with either Tomas Rosicky (7) or Lukas Podolski (9) but he appears to have chosen the figure formerly taken by his old Barca teammate Alex Song
Nacho Monreal who occupied that No. 17 willingly handed it over to his new teammate and the Spaniard has now moved to No. 18.
