Ange Postecoglou is set to welcome Anthony Ralston back - as he sweats over the fitness of Greg Taylor ahead of Thursday’s Europa League trip to take on Real Betis.

Taylor aggravated a shoulder injury in the weekend win over Ross County and is a major doubt for the Group G opener in Seville.

The left-back missed the Rangers game through the injury and now looks to have suffered a recurrence.

The Scotland international has been sent to see a specialist to try and get to the bottom of the issue, but it looks like the next European outing could come too soon.

The positive news for the Hoops is that Ralston is now back in full training and will be available for the trip to Spain.

It would give Postecoglou options to cover if Taylor doesn’t make it.

Ralston has been one of top performers in recent weeks.

Ralston’s return could see Josip Juranovic moved to left-back in the set-up that the Celtic boss adopted against Rangers or he has the option of throwing in young Adam Montgomery, who came off to replace Taylor on Saturday.

Postecoglou also has concerns at the top end of the pitch.

Kyogo Furuhashi is out for around a month with a knee injury that he suffered away on international duty.

New signing Giorgos Giakoumakis is also still to make his debut after missing the win at the weekend.

It remains to be seen if the Greek frontman will be available for Thursday.

If he isn’t then it would leave Albian Ajeti, who scored a brace at the weekend, as the club’s only out and out striker.
