Celtic have been warned that they will need to invest heavily in their playing staff if they want to go on and win 10 in a row.
Former Hoops player Mark Wilson has outlined what the club need to do if want to continue their dominance in Scotland, as reported by the Evening Times.
Celtic look set to go on and win another domestic title this season, taking them to eight in a row.

With the club so close to achieving 10 straight title wins, Wilson is eager to see those behind the scenes step up to the challenge and provide the necessary funds for whoever may be in the dugout next season.
Peter [Lawwell] and the club will need to throw a good bit of money at this because Celtic can’t afford to fail. Rangers have put up a decent challenge this year and you’d think they will be stronger again next seasons.
It would be catastrophic if they didn’t do nine and the fans would never forgive the board if they didn’t splash the money.
Celtic face the prospect of losing a core group of players over the summer, with Dedryck Boyata out of contract, while a number of loan stars are set to leave.
