Long time lurker, first time poster.
I would dispute the portrayel of him as not being respectful. In the summer, he preemtively said no to everyone except Real Madrid and Barca. I think that shows that he values being at Tottenham quite a lot, but that the pay has to be appropriate to his value in the team. During their entire time at Tottenham so far, avg. wages are approximately as follows:
Eriksen: 2.52 mil. pr. year - (6 seasons)
Kane: 4.37 - (5 seasons)
Alli: 3.16 - (4 seasons)
Son: 3.84 - (4 seasons)
Lamela: 3.44 - (6 seasons)
Eriksen was bought for next to nothing, and has been paid "next to Winks". Levy would not give Eriksen parity with Kane and expected him to sign eventually, but Eriksen called his bluff. Now, Levy has instead given financial parity with Kane to Ndombele. If neither Barca nor Madrid want Eriksen in January, Levy could offer him parity and a hefty sign-on bonus to make up for lost ground, and Eriksen would probably sign.
