The 27-year old Swiss gloveman has completed his move on a two-year deal to KC Stadium and Bruce is thrilled with what he has at his disposal after also signing Ben Amos on loan from Manchester United.
"We knew we needed to act and in the last couple of days we've got two goalkeepers in who will do very well for us I'm sure," Bruce told the Hull Daily Mail. "It was imperative that we brought a couple in and I'm very happy with that area now.
"There's a bit of competition there that can only stand us in good stead. I've not brought either goalkeeper in with the assumption he will be my No.1, gone are those days.
"I'll have a big decision to make over the next four or five weeks but the challenge for both is to grab that jersey.
"Eldin was on trial here and big Gary Walsh, who worked with him, said he'd done everything that was asked of him. There was some sort of deal in place from before so knowing what he was capable of on a Bosman transfer, it was something we've opted to push through.
"Ben is very highly rated but he knows he needs to go and play somewhere," added Bruce. "It's a difficult job when you're a goalkeeper because you can get to 22 or 23 and you've not played."
