That was naruto's forehead protector. And if you look at the one piece cover for the latest chapter, you'll realise that kishi was just thanking oda for his tribute and celebrating their rivalry of 15 years.

That's not the case.
Just as a few members have stated, Kishi and Oda are both good friends. Kishi had visited Oda when the latter was hospitalised, and they sometimes commented each other's works in WSJ mangaka/editor comment sections.
While Naruto has Mugiwara JR,
Oda draws a whole cover page of this week's One Piece chapter fully dedicates to Naruto, with a title of 'SMILE'. The scene is where Luffy eats a ramen and facing him is supposed to be Naruto eats a meat with bone in it (they exchange their favourite foods), but Naruto is sort of covered behind Nami, whom is Luffy's navigator and wears a one piece attire with Hidden Leaf symbols patterned it all over. Others that present atm are Chopper (Luffy's doctor) and a chibi fox.
Even the One Piece logo above the scene has been modified, with the letter O is replaced by Hidden Leaf symbol and the letter I (where it supposed to be Luffy's silhouette figure) has been changed into Naruto's silhouette figure. The first letter E has shuriken at the middle tip.
