Danny Rohl has "total" belief Rangers can win the Scottish Premiership but has called on his players to back it up with "consistency".

Rangers have picked up 46 of a possible 57 points since Rohl took charge in October and last Sunday's 4-2 win over Hearts moved the Ibrox side to within two points of the Scottish Premiership leaders.

However, Celtic, who are a point behind Rangers, have a game in hand on the top two.

"I totally believe we can do it," Rohl said before Sunday's league trip to face Livingston.

"There's no doubt about the strength of this squad now. It's now about consistency but we are still in second position not in the first position."

And he added: "The last couple of weeks was fantastic but I think it was a good statement.

"We have to continue. We have to keep our intensity, I think this is crucial. We know these games you have to take a win because otherwise it makes no sense to win the game before."

Rangers announced on Thursday that Scotland defender John Souttar had signed a new contract until the end of next season, with the option of a further year.

"It's important that we have leaders, to continue with them, not just on the pitch but off the pitch," Rohl said of Souttar, 29.

"He leads the group. It's important to have a core together to build something around."

Rohl has injuries to contend with this weekend and suggested there would be "two or three changes".

However, midfielder Connor Barron and defender Derek Cornelius are making progress in their returns to fitness and could feature in March.
