He had joined the team long ago but today Inter made it official that Christian Ansaldi has joined Inter from Genoa CFC on a permanent deal. So far the player has been quite impressive in pre-season friendlies. Inter today also confirmed on their website that Diego Laxalt has made a permanent move to Genoa FC.

I thought this article can be more informative about how much it cost, his salary, etc
Had a great season with Genoa, if he can replicate that form he will be our best fullback. But for some reason I think Mancini won’t play him just because he can be a wanker.
Why he only played 9 times during his 3 years at Zenit…and also a few in Athletico…hmm..
