It is not odd... it is a usual move by Bayern, buying every well gifted player away from its Bundesliga competitors. Bayern also is interested to buy Robert Lewandowski.
I could name you over 30 players who were bought by Bayern from a national competitor and only a handfull of those made impact on the field.
Best example might be Lukas Podolski who was transferred from Cologne to Bayern and went back after just three years before joining Arsenal.
Well that's what they signed him for. He was doing it every week at Arsenal.
As for Suarez, well yeah, he's a bit of a dickhead, and apparently a bit of a psychopath. Should he be banned from playing football though?
I think he's genuinely got a mental illness and the club should sort it out. There's no point in the English FA banning him because he'll just go play somewhere else and do the same thing again. He needs treatment. Plus of course he's one of the best forwards in the world and it would be a shame if he went to play somewhere else.
Meanwhile, someone bring back Balotelli. This season has been dull without him.
