Mark Warburton has revealed he would make the same attacking substitution against Celtic, if Rangers are losing their Old Firm clash on Sunday afternoon.

Manager Warburton substituted centre-back Rob Kiernan for attacking midfielder Harry Forrester in the 72nd minute, when his side were losing September’s league clash 3-1.

The tactical change proved to be costly, as minutes later Phillippe Senderos was sent off, which resulted in the Glasgow club losing the Old Firm tie 5-1.

Warburton was criticised and questioned by supporters for his tactical change, as the Gers were humiliated by their rivals at Celtic Park.

Now both teams are set to meet at Hampden Park for the Scottish League Cup semi-final on Sunday, with Warburton revealing why he would make an attacking substitution.

“Well, at 3-1, we would do,” said Warburton, as quoted by STV. “What we can’t allow for is the sending off but that doesn’t get mentioned. The fact is that at 3-1 you’ve got to be attacking in your decision making.

“Would we do the same again right now? Absolutely. But you have to look at every aspect of that game and say ‘where can we learn?”

The last time Warburton’s side beat Celtic was during the League Cup semi-final last season, when the Gers defeated their rivals on penalties, while they were still a Championship club.

Now they are set to meet in another mouth-watering contest, with the Ibrox club looking to win back the bragging rights, following their humiliating defeat in the league in September.

In other Rangers team news, the club’s senior man has revealed what he could not do following the 5-1 defeat against rivals Celtic.
