From BBC sports live: 1111 FOOTBALL: - Germany defender Per Mertesacker has described his impending arrival at Arsenal as like "before the first day at school". The 26-year-old moves to London on Thursday following his Deadline-Day signing and says: "I have a new challenge in a new country, a new style of play and a new language [but] I am ready for it." Great to hear a player look forward to playing for us, especially a top International defender. Hopefully his arrival will give our defence a much needed German efficiency!
