Graham Potter insists he is not “naive” enough to expect a happy homecoming when he takes his Chelsea side to former club Brighton on Saturday.The 47-year-old coach left the Amex Stadium last month to replace Thomas Tuchel as Blues boss and has yet to lose a game with his new club."These things happen in football, sometimes you get these opportunities and you have to take them or not," Potter said."It's about a decision and the decision to work here was too good to turn down."
