BARCELONA, Spain — Cameroon midfielder Alex Song is set to sign with Barcelona after Arsenal agreed on Saturday to sell him, one day after Robin van Persie left the Premier League club.

Barcelona says the transfer will be €19 million ($23.4 million) and Song will sign a five-year contract after he travels to Spain to agree personal terms and undergo a medical examination.

The 24-year-old player will be presented on Tuesday.

Song will help replace Seydou Keita, who left during the offseason to play in China, and provide some muscle to a talented but lightweight midfield that is led by Andres Iniesta, Xavi Hernandez and former Arsenal player Cesc Fabregas.
