Alex Song has concerns over Arsenal's move for Rennes midfielder Yann M'Vila.

The Daily Express says Song will seek assurances on his Arsenal future from manager Arsene Wenger as the club attempt to finalise their year-long pursuit of M'Vila.

Song's current Arsenal contract runs until the summer of 2014 and is worth around £55,000-a-week.

But having made over 40 appearances and produced a number of assists for Robin van Persie this season, he will seek an extension and a substantial pay rise.
