Ex-Toronto striker Defoe told the Transfer Talk podcast, "I don't think he'll regret because it's a good league, a league that seems to be improving every year. All the stadiums are full, the atmosphere, the facilities are always good.
"I think he will enjoy it to be honest and he will be a massive signing for the football club as he's a massive name. He can help the younger players there by bringing in so much experience.
"The league will be buzzing as it's another big name. It helps the league grow as well and it'll probably attract other big names.
"When you have been in that bubble for so long, sometimes it gets to a point where you want to breathe and try and live your life."
