The Saudi Pro League is interested in Martinez's services, and he has also held talks with a talent agency run by a well-known sports agent. If Martinez leaves, Espanyol's goalkeeper Joan Garcia is likely to replace him, but he is also wanted by several other top clubs. Garcia has been outstanding in La Liga this season, earning interest from Manchester United among others.

Martinez has made 50 appearances for Aston Villa this season, keeping 13 clean sheets. While he will be difficult to replace, the club may decide to sell him for a profit before finding a new goalkeeper. This could be a strategic move by Unai Emery to bring in a younger and more exciting player.

Emery is expected to invest in new players in the coming months, and selling Martinez could be part of his plan. The club will likely consider offers for the Argentina international goalkeeper if they feel they can find a suitable replacement.

Martinez's profile as a World Cup winner makes him an attractive target for other clubs, but his age may be a concern for Aston Villa. The club will weigh the pros and cons of keeping him versus selling him and bringing in a younger player.
