There has been a long-running debate about pitches in Scotland, and that has only been intensified after Rangers striker Martyn Waghorn suffered a major injury against Kilmarnock earlier this month.
Rangers were facing Kilmarnock in the Scottish Cup, and forward Waghorn suffered a knee injury, with the Gers suggesting that the plastic pitch at Rugby Park was largely to blame for that.
Now, the debate has intriguingly sparked a row between the Old Firm clubs, Rangers and Celtic. As quoted by BBC Sport, Celtic boss Ronny Deila suggested that anybody who thinks football should only be played on grass is 'old-fashioned', whilst Gers manager Warburton reacted angrily, calling the Norwegian 'disrespectful' for his comments.
Many pitches in Scotland are now plastic, and the debate continues to rage on over whether that's the best step for player safety right now.
Now though, former Celtic striker John Hartson has waded in, telling The Scottish Sun that he thinks Warburton is being 'pathetic' by stoking an argument with Deila.
A clearly outraged Hartson continued even further, stating that Warburton has enough to worry about at Ibrox in terms of signing players and winning promotion, before hinting that he thinks Warburton couldn't handle the pressure of an Old Firm derby.
"Who the hell does Mark Warburton think he is to come out and criticise the Celtic boss?" said Hartson. "Deila has a lot to answer for. But if he thinks Warburton’s views on astroturf pitches are old-fashioned then he’s entitled to say it. I must have missed something as last I heard Rangers were a Championship club. Celtic are four-in-a-row Premiership champions, so if anyone should be showing some respect it’s Warburton.
"You would think he would have enough to worry about at Ibrox. Warburton should just concentrate on winning promotion and getting some money for new players. Starting a fight on how good or bad plastic parks are is just pathetic. Warburton just seems to get bothered about things which I don’t think he should be too concerned about. And it begs the question: What’s he going to be like when Rangers win promotion to the top flight?
"More to the point, what’s he going to be like when he’s in the eye of the storm at an Old Firm game?" Let me tell you, Mark, this is a stroll compared to what you have coming. You shouldn’t be sweating over the small stuff. I honestly cannot believe Warburton had a go at Deila for saying what he said," he added
Do you think the Deila-Warburton situation has got out of hand?
