Hi maarten. Your picture was a bit fuzzy so I was a bit reticent to try to name it. I believe that there is a VERY good possibility that it is a Brazilian Pink Birdeater. There are just so many different kinds of tarantulas that look similiar, without a really sharp image, it does make it difficult to completely confirm. Here are some other pics of one and other info for you to look at.
