Alistair Johnston Interest

As a Celtic and Everton fan I don’t understand why some of us Everton fans don’t want Johnston. I don’t want him to leave Celtic but if he was to leave I would be delighted if he came to Everton. He is Canada’s starting right back at the last 2 world cups and had a pretty good 2026 World Cup with him also having champions league experience. So tell me Everton fans that don’t want him why do you not want him.
