After several months of dealings, the summer transfer window is officially coming to a close tomorrow.
During this summer we have seen several interesting moves. We saw the likes of Cesc Fabregas and Samir Nasri leave Arsenal, a new goalkeeper in David de Gea at Manchester United and a ridiculous transfer for Samuel Eto'o to Anzhi Makhachkala in the Russian Premier League.
