Those are not real fans but twitter toxic fanbase.
In that case every fanbase does that, rohit fans tell you he is greater than virat and vice versa.
By the way it was not he's fault he was given MoM in 2011 WC final and he publicly never speaks about gambhir being not important part of win or give him credit it's just toxic fans. You want to only take toxic fans into account then good luck becoz I can show u virat and rohit toxic fanbases as well.
