For a cost of around £10 million and at 23 years of age, Thomas Vermaelen has the potential to plug the gap that has leaked so many goals in the Arsenal defence.
He has plenty of European and International experience, but the Premier League is much stronger than the Eredivisie and it may take a Vidic-like period to adjust to the pace of English football.
However, despite being a good defensive acquisition, the problems in the combative department of midfield still remain to be solved.
