Arsenal and Manchester City are watching Bayern Munich midfielder Javi Martinez very closely after the Spanish midfielder reportedly instructed his advisor to search for new club thanks to growing frustration over a lack of playing time.
Martinez enjoyed a dream debut season at Bayern after signing for a club-record €40m in 2012, helping the German giants win a historic treble, but has fallen down the pecking order under Pep Guardiola this term and been restricted to just 13 Bundesliga starts.
Guardiola's methods have delivered more domestic success but left Martinez with a growing sense of frustration over his role in the side, to the extent that Bild believes the 25-year-old now has his heart set on a summer switch.
The versatile star's representative Margarita Garay is now on the lookout for potential transfer suitors and Arsenal and City are two clubs cited as keeping tabs on the situation by Bild, as they both look to strengthen this summer.
Arsenal in particular could use the midfielder's energy, dynamism and positional awareness in his preferred central midfield position, although the Gunners would probably have to get close to the £42.4m spent on Mesut Ozil to force through a blockbuster transfer deal.
City meanwhile are set to have their summer transfer plans hampered by the looming threat of sanctions from UEFA as they look to enforce new Financial Fair Play rules, but Martinez is still a player that interests the club in the long-term.
Guardiola is now facing the prospect of holding summer talks to persuade the stand-in centre-back that he should put off any plans to leave the Allianz Arena, although with the player under contract until 2017 Bayern are very much in the driving seat for any transfer negotiations if they do receive a concrete offer.
