Robert Lewandowski has finally been unveiled as a Bayern Munich player having officially completed his long awaited move from Borussia Dortmund.

The Polish striker, who signed a pre-contract agreement with the record breaking Bundelsiga champions back in January, left Dortmund on a free transfer upon the expiration of his contract at the end of June.

Holding a press conference to mark the unveiling, Bayern posted pictures and updates via their official Twitter account.

One Tweet revealed the 25-year-old will be wearing the shirt vacated by Mario Mandzukic, who is expected to leave the club for Atletico Madrid in the coming days. It read, "#Lewandowski will be hunting for goals for #FCBayern in the no. 9 shirt. Good luck, Robert!"

Speaking positively about his arrival, Lewandowski said, "Every season at FC Bayern is about winning titles, I know that. We will have to work hard. It's going to be good. I can get even better at FC Bayern and win even more titles.

"I feel really, really good. My batteries are fully recharged."

Bayern Sporting Director Matthias Sammer added, "[Lewandowski] is incredibly flexible and has all the attributes that a footballer needs."

Over the past few seasons Lewandowski has blossomed into one of Europe's finest goalscorers. In 185 total appearances for Dortmund he scored 101 times and he will surely be a great asset to what is already one of the best club sides of the last 20 years.
