Celtic defender Alistair Johnston faces an injury sweat to be fit for the beginning of the Scottish Premiership campaign.

The 24-year-old has reportedly yet to return to pre-season after sustaining a knock while on international duty with Canada.

This is according to a report from the Scottish Sun which claims that the right-back could miss opening matches of the season in a huge blow to Brendan Rodgers.

He played for his country in June but was left out of the Gold Cup squad with manager John Herdman admitting he was still feeling the effects of the ankle injury.

Speaking last month, Herdman said: "Some players need a break to recover from injury.

"Alistair Johnston was carrying an injury he picked up on club duty with Celtic.

"So we've got some young lads that we'll start looking at for this Gold Cup.

"I would have loved to have the same squad as for the Nations League, but it won't happen."

This leaves the Hoops with Anthony Ralston as the only right-back option. Will they look to strengthen in the transfer market before the beginning of the competitive season.

Meanwhile, Brazilian winger Tete has announced he has left Shakhtar Donetsk with immediate effect and has revealed there are a host of clubs chasing his signature.

Reports in Ukraine have suggested Celtic are "strong favourites".

The 23-year-old spent last season on loan at Lyon and then Leicester City where he worked with Brendan Rodgers.

And the former Liverpool boss spoke in glowing terms about Tete after he joined the Foxes on loan and scored on his debut against Aston Villa.

He said: "Tete was what I have been talking about for 18 months – a right-winger that can take the ball, pass the ball, look after it, make runs and work.

"What a debut for him. It was really good. He knows football, he knows the type of game we were trying to play, and his touch is immaculate.

"He has a good weight of pass but can run in behind. His finish was absolutely brilliant. He loves football off the pitch and he is super professional."

Could the duo be set for a reunion at Parkhead?
