Arsenal have complete the signing of France defender Mathieu Debuchy. The defender has been on Arsenal's radar for a long time until a fee was agreed after France's elimination at Brazil. The deal was however put on hold so Newcastle could find a replacement and Daryl Janmaat was subsequently brought in to replace him at Newcastle. The 28-year old represented France at the World Cup in Brazil and was preferred to start ahead of Bacary Sagna for four out of five matches. Although the total sum paid by Arsenal could not be verified at the moment, it was learnt that the deal was made for £8million and performance related add ons could follow. The France international becomes Arsenal's second major signing of this transfer Window and proves manager Arsene Wenger's intention of challenging for top honours as soon as the season starts. Now I wonder what Michael Owen was smoking when he said yesterday that Arsenal will drop out of top four even when Alexis Sanchez was already brought in.
