Celtic have been working on deals to sign both Sunderland striker Charlie Wyke and Brighton goalkeeper Mat Ryan, Football Insider report.

The Lowdown: McKay and Postecoglou's Wembley meet up

New Celtic CEO Dominic McKay and boss Ange Postecoglou met in person in London on Friday, with the pair continuing to work on preparations for the new season.

The pair were also in attendance at Wembley, watching England against Scotland at the European Championships.

Current Celtic midfielder Callum McGregor played the entirety of the Group D stalemate, and it seems as if the Hoops were also busy on Friday when it comes to getting some new faces through the Parkhead door.

The Latest: Source shares transfer news

Former Celtic man and Football Insider pundit Frank McAvennie was talking to the site about the Hoops’ summer business in a story which was published on Friday.

Within that piece, Football Insider added that the club are working on deals for both Wyke and Ryan after being informed by a Hoops source on Friday.

Wyke is set to be out of contract at the end of month, whereas Brighton are happy to part ways with Ryan this summer.

The Verdict: New additions are needed quickly

Celtic have a month until Postecoglou’s first competitive game as Hoops boss against FC Midtjylland in the Champions League qualifying rounds, so new signings could do with being sealed very soon.

Postecoglou is also set to take training next week after completing his quarantine, so you’d think he’d want his targets through the door as quickly as possible ahead of the new season.

Wyke and Ryan appear to be the two targets Celtic are working on at this moment in time, and hopefully, deals can be reached sooner rather than later, perhaps with a view to getting both players ready to start in Postecoglou's first competitive XI against FC Midtjylland.
