Celtic manager Ange Postecoglou says the club is still 'active and alert' in this transfer window as he eyes further signings.

The 56-year-old has already acquired seven players this summer - permanent deals were concluded for Daizen Maeda, Cameron Carter-Vickers and Jota while Benjamin Siegrist, Alexandro Bernabei and Aaron Mooy have all joined.

Moritz Jenz has also signed up on loan for the season from FC Lorient with an option to buy.

But the Hoops manager concedes he's not yet done looking to strengthen his squad, with more than one area still of interest.

"We are still active and alert and still looking at some possibilities as I think we can still strengthen in a couple of areas,” he said.

"It has to be the right one, the right player with the right type of profile. While the window's opening there's always stuff happening incoming and outgoing so we will see how things pan out."

Postecoglou's side defeated Norwich City 2-0 in their final pre-season friendly at Parkhead on Saturday afternoon thanks to goals from Maeda and David Turnbull.

The Hoops open up their Premiership title defence against Aberdeen on July 31 - but could be without central defender Carl Starfelt due to injury.

"We're hoping he'll join in training at some point this week,” Postecoglou said.  “He's in the last stages and doing all the physical stuff away from the group.

"So, knock on wood, he's passed every stage and the handover to the football department should happen next week.

"That means that hopefully within a week or two he's ready to go.”
