Signing is finished, as a Benfica follower in Portugal I'm happy with this....Aimar has one moreyear left and then he's done imho, so witsel will slot right in next season, while still getting a lot of playing time this year.
Good move by axel. Just playing in belgium won't help in the development of these talented ypung belgian players. Wish defour, Lukaku, De bruyn(also Hazard, cause I think he is done with Lille) and many others makes their desicion quickly.
