Speculation continues to ramp up around Matt O'Riley's Celtic future - with Atalanta and Juventus among the clubs battling for his signature.

Some reports in Italy even claim the Hoops midfielder has already verbally expressed his desire to leave Scottish football this summer and that further bids have been tabled. 

Despite that, O'Riley has travelled with his Celtic teammates on their flight over to the United States, where they are set to face Chelsea, Manchester City and DC United in a glamour pre-season tour. 

Brendan Rodgers will be hoping the 23-year-old can put any transfer talk on the back burner for now until any official agreement is made.

There is also a new face among the Celtic contingent heading across the Atlantic. Goalkeeper Viljami Sinisalo is set to be officially announced as the latest signing after sealing a £1million switch from Aston Villa. 

Sinisalo shined on-loan at Exeter City last season and previously had a productive spell in Scotland with Ayr United. 

He will now compete along side Scott Bain, Benjamin Siegrist and Tobi Oluwayemni in Celtic's goalkeeping department - with the impetus still on finding the perfect successor for Joe Hart, who hung up his gloves following last season's Double-winning campaign.

The Celtic squad also welcomed back several key players who had represented their national teams at the recent Euro 2024 tournament. This included Scottish internationals Callum McGregor, James Forrest, Greg Taylor, and Anthony Ralston.

Additionally, the team was boosted by the return of Japanese duo Reo Hatate and Daizen Maeda. These individuals had been given additional time off following their international duties and were now rejoining the Celtic squad after missing the previous exhibition matches against Ayr United and Queen's Park this month.

There was space for Gustaf Lagerbielke and Mikey Johnston, even though their long-term futures remain unclear. While the £3.5million acquisition of Paulo Bernardo from Benfica appears to be edging closer.
