Rakitic was outstanding in the heart of midfield during Croatia's 3-0 victory and, alongside Marcelo Brozovic and Luka Modric, looked imperious. He broke up Argentinian attacks effectively, recycled possession impressively and even picked up a goal right at the end of the match to round off a brilliant 90 minutes.
He has been a Barcelona player since 2014 and has cemented himself as one of the world's best midfielders in the process. Given the talents the Catalan giants have at their disposal, it is a testament to Rakitic's abilities that he has been able to remain a first team regular for the four seasons he has spent at the Nou Camp.
But some Arsenal fans are beginning to dream that there is a slight possibility that the Gunners will be able to bring the Croatian over to the Emirates next season following his performance against Argentina.
There is nothing to suggest that any sort of bid is being prepared by Arsenal, but that hasn't stopped some supporters from dreaming.
Here is a collection of tweets from some optimistic Gunners.
Given his current £50m valuation, it is unlikely that we will be seeing Rakitic in an Arsenal shirt any time soon.
Newly appointed manager Unai Emery has a limited budget and there are plenty of other cheaper alternatives currently being linked to a move, including Sampdoria midfielder Lucas Torreira. However, there is nothing stopping Arsenal fans from remaining optimistic.
