Ange Postecoglu told ‘one-dimensional’ approach won’t win Premier League

Celtic boss told to change tactics and sign new players if he wants to win the league

Celtic manager Ange Postecoglu has been told that his "one-dimensional" approach will not be enough to win the Premier League.

Pundit Chris Sutton has criticized the Australian's tactics, saying that he needs to change things up if he wants to be successful in Scotland's top flight.

Sutton said: "Celtic are too one-dimensional at the moment. They just play the same way every week and it's not working. They need to be more flexible and adaptable."

Postecoglu has also been told that he needs to sign new players if he wants to win the league.

Former Celtic striker John Hartson said: "Celtic need to sign some new players in January. They need a new striker and a new centre-back at the very least."

Hartson added: "Postecoglu has done a good job so far, but he needs to strengthen his squad if he wants to win the league."

Celtic are currently top of the Premier League, but they are only two points ahead of Rangers.

Postecoglu's side has been in good form recently, but they have struggled against the better teams in the league.

If Postecoglu wants to win the league, he will need to find a way to beat the best teams in the league.
