Celtic will be looking to continue their perfect start to 2019 when they travel to St Johnstone in the Scottish Premiership on Sunday, live on Sky Sports.

Brendan Rodgers' side have won all four of their matches this year, scoring 12 goals and conceding none. Their victory over St Johnstone in midweek saw them extend their lead at the top of the table to six points.

"It's an advantage but it's not a huge advantage," said Rodgers. "There's still a long way to go so we'll be focused for the upcoming games."

Celtic strengthened on Deadline Day with the signing of full-back Jeremy Toljan from Borussia Dortmund. However, Rodgers has said he will need to be assessed before Sunday's clash as he needs to gain match fitness.

St Johnstone have slipped down to sixth in the table after losing their previous two matches.

Ahead of Sunday's encounter, Rodgers revealed Tom Rogic is out for six weeks with a knee injury.

He added: "Tom is actually going to be out for six weeks which is a real blow for us.

"He came back from the Asia Cup and had an issue with his hand out there and got injured with his knee when he landed awkwardly.

"He went down to London with a member of our medical team yesterday to check that his hand didn't need an operation and while he was there we thought we would have his knee looked at and it showed up that a lateral meniscus problem which is going to put him out for up to six weeks."

Team news

Rogic is out with a knee injury which will keep him off the pitch for six weeks.

New signing Toljan will be assessed ahead of the trip to Perth but defender Filip Benkovic is out for four to five weeks with an ankle problem.

Dedryck Boyata (abductor), Anthony Ralston (ankle), Olivier Ntcham (hamstring), Kieran Tierney (hip), Eboue Kouassi and Daniel Arzani (both knee) remain out. Leigh Griffiths is out of football for a period of time with personal issues while new striker signing Vakoun Issouf Bayo is still getting up to speed.
