Barcelona chief Josep Maria Bartomeu is in London today for talks over Arsenal midfielder Alex Song.
RAC-1 says Barca cannot wait any longer for Arsenal to decide whether Song is available and Bartomeu is now in London to push talks along.
Barca have already tabled a €15 million offer for the Cameroon midfielder, but the Gunners are yet to respond.
Arsenal are understood to be seeking €20 million for Song, while Barca are hoping for a compromise of €18 million.
