"Arsenal defender Per Mertesacker has made a silent boast about the club's summer transfer signings. Arsenal centre-back Per Mertesacker published a silent boast about the club&amp;rsquo;s summer transfer signings through his Instagram account. The German posted a picture with the hash tag &amp;lsquo;Arsenal&amp;rsquo; which showed off Mathieu Debuchy, Alexis Sanchez, Calum Chambers and goalkeeper David Ospina. The defensive arrivals of Debuchy and Chambers are superb additions to the back four because they cover so many roles in the back four. Debuchy guarantees Premier League experience while Chambers can play at right-back, centre-back and also a holding role in midfielder. Arguably the most significant of the summer signings is Alexis Sanchez from Barcelona, who arrived in a &amp;pound;32 million deal and will be installed on Arsenal&amp;rsquo;s left hand side. Sanchez also showed during the World Cup with Chile that he&amp;rsquo;s a good enough player to feature through the middle.
