Klose, 29, will have a medical on Thursday before signing a four-year contract and is due to start training with Bayern on Friday.

Bayern are believed to be paying an initial fee of 12 million euros (16.2 million dollars), but the final deal could be worth as much as 15 million euros depending on Klose's performances.

The fee for one of Europe's best forwards was relatively low because he would have been able to leave Werder on a free transfer at the end of the 2007-2008 season.

Klose will be expected to form a striking partnership with Italian World Cup winner Luca Toni, who joined from Fiorentina in an 12-million-euro deal, and Bayern spent 25 million euros on French midfielder Franck Ribery to bolster a team that finished fourth in the Bundesliga last season and failed to qualify for the Champions League.

Klose scored five goals to finish top scorer at last year's World Cup in Germany and has scored 33 goals for his country in 69 appearances.
