Mark Hateley insists Rangers need to start Alfredo Morelos and Fashion Sakala if they are to have any chance of beating Celtic today.

The former Ibrox striker has backed the Colombian to start ahead of Antonio Colak and he reckons Sakala's pace could cause problems.

Morelos was criticised earlier in the season for his physical condition and also his attitude, but he appears to have found his form again under the leadership of Michael Beale.

Hateley told BettingSites.co.uk: “I would play Fashion Sakala. He has hurt Celtic and caused them problems in three of the last four meetings. He set up the two Rangers goals in the 2-2 draw in January, he scored at Parkhead last May and it was his persistence that gave Rangers the winner in last season’s Scottish Cup semi-final.

“He plays at such a pace. Everything he does is quick, he is direct and he is a handful. I think there is even more to come from Fashion because he needs a little more composure in front of goal and he needs to mix his game a little bit.

“All defenders are worried about facing guys with pace. He will try to get in behind and defenders hate to be turned and having to run back to their own goal.

“Alfredo Morelos has to play up front for Rangers. He brings a lot to the game outside of the box – a lot more than Colak – and he has the experience of this fixture.

“Morelos has also shown he can play against good defenders in good teams. He has the equipment to deal with it. I would like to see him pin defenders a bit more and get them half-turned.

“The other aspect is that Morelos is out of contract this summer so if he is leaving and wants to find a good club, this is the stage he must perform on."

Speaking to the media earlier this week, Sakala said: “I know how important the game is when you play against the other mob.

“It’s all about the badge. I don’t really think about my performance, the most important thing is the win for the fans and the club.”
