De Boer was at Inter for like three months anyways. Gabigol hardly impressed their other managers either. He simply wasn't good enough and that has nothing to do with De Boer.

Dude simply was rubbish. Lazy, no work ethic, and fucked around when on the pitch. Hardly the managers responsibility to deal with poor purchases.
That'd be like bashing Allegri for not turning Sturaro into Vidal. Though I'm sure someone on this forum would do that.
