Martinez has been linked with a move away from the Basque Country club for a while now and it seems as though the Bundesliga side will beat both Manchester City and United to his signature.
With a lot of work still to do in the deal though to meet the Spanish clubs demands, Bayern may not be able to sign him before the month is out.
Bilbao bosses are sure to do all they can to keep one of their star players at the club and will know that the fans are likely to react badly to one of their prized assets leaving the club.
The German team are looking to secure his services within the week though and will know that he could play a key part in their title challenge this year.
Josef Heynckes is also looking to go one better in the Champions League this campaign after losing on penalties in the final last time out.
Martinez is certainly one of the most highly-rated players in European football at the moment and can play either in defence or midfielder so if extremely versatile.ayern Close in on MArtinez
