Mauricio Pochettino is warming to the idea of video assistant referees being added to the Premier League following a number on contentious decisions in the north London derby draw with Arsenal.
The Tottenham manager has long been against the introduction of VAR, which was voted in by Premier League clubs and will be introduced to the competition from next season.
The Argentine complained about a decision regarding a Granit Xhaka challenge early on in the derby at Wembley Stadium, minutes before Aaron Ramsey scored to give Arsenal the lead.
There were too questions from Gunners boss Unai Emery over a challenge from Danny Rose on goalkeeper Bernd Leno as the hosts pushed for a second half equaliser, while the penalty given against Skhodran Mustafi was soft at best.
Pochettino, though, appears to be changing his stance on the introduction on VAR, but warned that football will never be a fair sport.
"From the beginning I wasn't too clear in the way that they are using it in different leagues,” Pochettino said.
“It's a massive experience for us to watch. I am following different leagues like France or Spain and the problems are happening the same. Nothing's changed too much.
“Some situations that are so difficult for the referee to handle or manage we cannot believe that it's going to be the key; that football is going to be fair. Football never was fair and it never will be.
“But of course in the way that we are going to use the VAR is going to be key,” Pochettino, who has previously said players, coaches and officials should be consulted on the implementation of VAR, added.
“I think with all the experience in the World Cup and the different leagues this season it's such important work to do now for the future to be sure that it's going to be a massive help for the decisions of the referee. It's going to try to be in some situations fair decisions for each."
Pochettino will get another closer look at the technology in action on Tuesday night when his side take on Borussia Dortmund in the Champions League, with Uefa having sanctioned the use of VAR for this season’s knockout stages.
