After completing his £19.75 million deal, the 22-year-old will add to Mikel Arteta’s right-back options, which currently include Cedric Soares, Caldric Chambers, and Ainsley Maitland-Niles.
The two games versus Man United, on the other hand, are the ones that some Arsenal fans are most looking forward to this season.
Mostly because Tomiyasu could once again combat his wits against Ronaldo.
As previously said, the pair are acquainted from their time in Italy, having crossed paths in a few Serie A games since the Japan international joined Bologna in 2019.
And one of those meetings has been talked about on Reddit.
Of course, this has garnered a brilliant, yet tongue-in-cheek, response from a few Gunners supporters.
TheSimpleShoe said: “No no I’m convinced. He’s better than Ronaldo, you can’t tell me otherwise.”
Havenexen said: “Scenes when Cristiano cant dribbles past Tomiyasu in Man Utd vs Arsenal.”
Dwarvenmasterrace said: “We brought him as a response to CR7 for United, bring it on!”
rbiopsy said: “CR7 must be trembling in fear now. The almighty Japanese young defender who once beat him on a dribble has followed him to England now!”
Arsenal makes the trip to Old Trafford on November 30 before hosting the Red Devils in the return fixture in mid-April and all of a sudden those two games have a bit more extra spice.
