Ange Postecoglou has warned Celtic's rivals they will be even better next season.
The Hoops landed back to back Scottish Premiership crowns following victory over Hearts at Tynecastle. They've secured a second domestic success of the season with four games to play and only Inverness standing between them and a Treble when the duo set to go head to head in the Scottish Cup Final in early June.
The champions have four games to play in the league and can still set a new points record by winning the final handful of matches. The Celtic gaffer has always been active and quick at getting his transfers done and he won't be resting on his laurels ahead of the new season. Postecoglou has previously admitted big name players could depart alongside new faces arriving in Glasgow. That could well be the case this summer but that doesn't faze the 57-year-old who faced a similar scenario with Josip Juranovic and Giorgos Giakoumakis in January.
