"Louis Laing is developing into a wonderful footballer, but he's missing tonight and Josh Law has played lots of games at right back, so there's not a problem there.

"We have three out of the next four games at home, which is important.

"What happens tonight has a huge bearing on what comes next."

Of course, there are more Premiership games tomorrow, featuring title hopefuls Celtic and Aberdeen. Can the Dons pip the faltering champions? Who will come out on top at Hampden on Sunday as Hibs face Ross County in the Scottish League Cup final?

Give us your thoughts on those, any other burning issues and, of course, tonight's match.

Japan goalkeeper Eiji Kawashima has failed to recover from injury sufficiently to start for Dundee United, but Luis Zwick still drops out, with Michal Szromnik taking over between the sticks.

Callum Morris is a surprise inclusion in defence, having been an injury doubt, while Gavin Gunning is also back to fitness, with Mark Durnan and Sean Dillon dropping out.

Motherwell boss Mark McGhee only makes one change and it is one that is forced on him following an injury to Louis Laing.

Midfielder Josh Law replaces the defender, so that could mean a change in shape or formation.

Rangers: Foderingham, Tavernier, Ball, Danny Wilson, Wallace, Holt, Halliday, Forrester, O'Halloran, Miller, McKay. Subs: Bell, Law, Clark, King, Shiels, Burt, Thomson. 

Greenock Morton: Gaston, Miller, Kilday, O'Ware, Russell, Barr, Forbes, McKee, McCluskey, McManus, Johnstone. Subs: Lamie, MacDonald, Scullion, McNeil, McMullan, Tennant. 

Referee: Nick Walsh

Motherwell: Ripley, Law, Hall, McManus, Hammell, Cadden, Lasley, Pearson, Johnson, McDonald, Moult. Subs: Ainsworth, Fletcher, Samson, Kennedy, Gomis, Thomas, McFadden. 

Dundee Utd: Szromnik, Donaldson, Morris, Gunning, Spittal, Rankin, Dow, Paton, Dixon, Anier, McKay. Subs: Dillon, Ofere, Knoyle, Murray, Durnan, Fraser, McGovern. 

Referee: Crawford Allan

Rangers are seeking their sixth straight victory, while Morton will be hoping for a more successful trip to Glasgow than last week, when they were eased aside 3-0 by Celtic in the Scottish Cup. 

However, there is hope for Jim Duffy's side as they drew 2-2 at Ibrox in their last visit there, in December.

Let's not forget there is also action in the Scottish Championship tonight, with Rangers looking to extend their lead at the top of the table over Falkirk to 15 points as they host Greenock Morton.

Motherwell thumped United 3-0 in their last meeting, in February, although it was the Terrors who came out on top on their last visit to Fir Park - 2-0 in August - and they are looking for a third straight victory there.

Both sides go into the game with a record of three wins in their last four outings, with Motherwell seeking a third straight victory.

Motherwell have suddenly found a bit form having themselves struggled despite the return of Mark McGhee as manager and a win tonight would lift them above Dundee and into the top six.

Dundee United remain eight points adrift of Kilmarnock at the foot of the table, but they have started to show some signs of life after a dismal start following the appointment of Mixu Paatelainen to replace Jackie McNamara as manager.

So you think Sunday's Scottish League Cup final between Hibernian and Ross County is the only show in town this weekend? Think again. 

Tonight's Premiership meeting between Motherwell and Dundee United has fallen somewhat under the media radar, but it is just as important as a national final for the relegation-threatened visitors at least.
