London has another new defender - they acquired Per Mertesacker representing Bremen for about 11 million euros.

Arsenal actively seeks to strengthen their defense after losing 2-8 to Man Utd in the Premier League on Sunday. On Wednesday, they also signed a contract with Brazilian Andre Santos.

In addition, the capital team should be supplemented by two new midfielders: Mikel Arteta from Liverpool's Everton and Yossi Benayoun, who wore the jersey of London Chelsea.

Last season, the 26-year-old Werder captain Mertesacker scored two goals in over 30 matches in the German championship.
