The 29 year old moved to Bayern Munich last summer but after Klinsmann’s sacking he has dropped down the pecking order.
Bremen general manager told the club’s official website: We are signing in Tim an experienced player, who will fit excellently into our young team.
“We have found a solution which is satisfactory for both sides.”
Bremen coach Thomas Schaaf added: “We are pleased that this transfer has gone through. We have already been able to celebrate some successes with ‘Boro’. He knows the set-up at Bremen and I think that he is looking forward to joining us.”
