Mourinho impressed with Alex Song's performance

Barcelona look set to sell two of their fringe players, with Chelsea on the brink of signing Alex Song and Martin Montoya keen on a move to Inter Milan.

Former Arsenal midfielder Song has spent the season on loan at West Ham, returning to London after his failed spell at the Camp Nou, and it now seems that Chelsea will extend the player's stay in the capital.

David Wright of the Express says Song has "impressed" manager Jose Mourinho with his performances over the past 12 months, and the Blues coach is said to be willing to pay £6 million to add the player to his Premier League-winning squad.

Wright says Liverpool and Arsenal have also expressed interest in the Cameroon international—but Chelsea's status as champions would surely give them the edge in any pursuit.

The 27-year-old was in top form for most of the season as the Hammers occupied the top half of the table, with Song featuring 28 times for the east London outfit, per Squawka.

And Matt Law of the Daily Telegraph says Song may yet remain at Upton Park, with the player said to be happy with new managerial appointment Slaven Bilic:

For a player of Song's ability and age, and considering he still has two years on his current deal, per Wright, the £6 million price represents a bargain for prospective clubs.

However, it is clear that Song is surplus to requirements at the Catalan superclub, and the EPL is the obvious destination for the midfielder, who spent six seasons playing for the Gunners.
