Worrying thing about yesterday is that's one of worst Hearts teams I've ever seen. Need Walker for Windass and 100% a new striker is a must.— Darren WATP (@Rangers54c) August 20, 2017
Walker was terrible the day. On that performance they can keep him— Zan the man (@ZanderWATP1) August 19, 2017

dorrans needs to sit further forward
get walker and moult to help Morelos
We need safe standing
What does that say about our set up. "Need to gel etc etc" It's below par at any level. Get Walker/McLean/Naisy/McInnes now!— EBT (@zulu09watp) August 19, 2017
Rangers are sixth in the Scottish Premiership table at the moment, while Hearts are currently seventh in the standings.
