Eyebrows were raised when the Premier League's bottom side last week named the 39-year-old as Mike Phelan's successor.
Some welcomed the move for a man likened to compatriot Jose Mourinho, others made disparaging remarks about the decision to plump for the former Estoril, Sporting Lisbon and Olympiacos boss.
Paul Merson and Phil Thompson were particularly aggrieved at the decision to appoint Silva instead of a home-grown coach judging by their diatribe on Sky Sports over the weekend.
"For me it's not important," Silva said, when asked about the pair's comments.
I respect all the opinions, what the football people talk, but for me not important really.
"For me what is important is my work with my players and what our fans feel, what our fans believe. That is what is important for me in this moment
sure, sure" before nodding in agreement.
