The Real Madrid trainer claimed earlier this week that certain people's votes in the elections were wrongly awarded to Del Bosque, a revelation that has since been denied by FIFA, but was backed by Macedonia skipper Goran Pandev Thursday.
"The situation does not bother me at all. To me, it is all a bit childish," Del Bosque stated to ONDA Cero.
"I don't want to give any further comments on it to avoid any misinterpretation.
"We have an important match against Finland coming up and that's all I'm thinking about at the moment."
Del Bosque was beaten to the prestigious individual award by Mourinho in 2010, but got his revenge in January when he piped the Portuguese to the trophy following Spain's Euro 2012 success.
Meanwhile, Napoli attacker Goran Pandev has backed Real Madrid coach Jose Mourinho's suggestions that the election for the Coach of the Year award was flawed.
FIFA has since defended the integrity of the managerial honour, insisting the list of votes published by the world football's governing body is accurate, but Pandev has stressed that his vote as Macedonia captain was wrongly awarded to Spain boss Vicente del Bosque.
"I voted for Mourinho," Pandev told La Sexta Deportes, even though the list published by FIFA has Pandev voting for Del Bosque, ahead of [Manchester City manager] Roberto Mancini and [Borussia Dortmund coach] Jurgen Klopp.
"I don't know what has happened here, but it is very strange.
"I told Mourinho I had voted for him, but I don't know what happened afterwards."
Mourinho eventually finished second in the election behind Del Bosque with 20 per cent of the votes.
