BERLIN Bayern Munich boss Jupp Heynckes refused to point the finger of blame at his defence as the Bavarians had to come from behind to draw 1-1 at Hamburg and lost their place at the top of the German league.Defending champions Borussia Dortmund finish the weekend back on top of the league, but only with a precarious two-point margin, with both Bayern and third-placed Schalke hard on their heels with 41 points each.After Hamburg’s Italian 20-year-old midfielder Jacopo Sala headed Hamburg into the lead on 23 minutes on Saturday, Bayern’s blushes were spared when Croatia striker Ivica Olic equalised just minutes after coming off the bench.Having seen his defence leave Sala unmarked for the opening goal, Bayern’s Heynckes refused to point the finger of blame at his team who have taken just four points from a possible nine in their last three league games."I don’t want to throw accusations at the troops,” said Heynckes, whose team play FC Basel in the first-leg of their Round of 16 Champions League clash on February 22.Dortmund deserved to go top after grinding out an impressive 2-0 win at Nuremberg as temperatures reached minus 11 Celsius on Friday night.
