Saw a post on reddit that yesterday G.Romero talked about his situation again.
The first problem is his wage demands, which other sources previously said it is 15M (English sources said 18M) along an expensive BO.
But in addition to that, Laporta was offended by the way Nico handled things last summer, Nico kept delaying response to the club and eventually he didn't trust them to register him (though, he got a point). Laporta remembers this, and he instructed both Deco and Flick to take him out of transfer list. Both Deco and Hansi had no issue with that as he wasn't their top target, but Laporta essentially ruled him as an option.
This is the second time Romero goes into the topics, around a week ago he stated that Nico isn't 100% ruled out, but to be considered, the club will need him to publicly "beg" to join us.
