England captain Alastair Cook lamented a "sour end" to the fourth Test with India after Ravichandran Ashwin confronted James Anderson over comments made about in-form India skipper Virat Kohli.
Kohli has been sensational in the five-match series, which India sealed by beating England by an innings and 36 runs in Mumbai, scoring 235 at the Wankhede Stadium having hit 167 and 81 in the second Test in Visakhapatnam as well another half-century in third Test in Mohali.
But Anderson, speaking after the fourth day's play, suggested the slow pitches in India minimise Kohli's flaws, saying: "Pitches like this suit him down to the ground".
Those words struck a nerve with India and specifically Ashwin, who accompanied Anderson to the middle as he walked out as England's final batsman on Monday.
"It was a bit of a sour end really," Cook said. "It was a disappointing end in terms of how well the spirit between both sides has been played.
"It was clearly in reference to what Jimmy said, which has kind of been blown out of all proportions, which it can do here. He was just stating a fact which if you asked Virat is probably quite true.
"But yes, it was obviously just sticking up for their captain which I thought was slightly unnecessary."
Kohli, meanwhile, moved to play down the incident.
"For the first time I was trying to calm things down in the middle at a time when [Anderson] is involved," he said. "Ashwin wasn't pleased with what he said in the press, but I didn't even know about it. So I didn't know what to make of it. I was laughing about it.
"Ashwin wasn't too impressed and he let him know, not using any bad words honestly. I think he told him he was pretty disappointed with what he said and it is important to accept defeat as it is.
"Things like that. Just general, you know how Ashwin is, he is to the point, he can really strike you well and he doesn't need to say bad words. Later on I told James these things happen and let's move on."
