Hull City have completed the signings of Peter Halmosi, George Boateng and Tony Warner ahead of the club's debut season in the Premier League.
Hungary winger Halmosi, 28, has joined for what is believed to be a club record fee of £2m from Plymouth Argyle.
Midfielder Boateng, 32, capped four times by the Netherlands, has arrived from Middlesbrough for around £1m.
Warner, 34, who is a Trinidad and Tobago international goalkeeper, was released by Fulham at the end of May.
Halmosi has signed on a four-year deal, while Boateng and Warner have both agreed two-year contracts.
Their arrival at the KC Stadium follows those of Craig Fagan, Geovanni and Bernard Mendy as manager Phil Brown continues to strengthen his squad for what promises to be a tough campaign.
Brown told BBC Radio Humberside he was delighted with the newest acquisitions.
"It's a fantastic day for Hull City, we've smashed the record transfer fee for Peter Halmosi, it remains undisclosed what we've actually paid but it's obviously more than a million pounds.
"We've also brought in George Boateng from Middlesbrough, who brings a wealth of experience, a Dutch international, 10 years in the Premier League and that's the type of player I've been looking for to bolster the squad we've already got.
"Last but not least, we've also brought in Tony Warner and he arrives to give us a bank of three keepers who can all play at Premier League level which is great for us.
"They're now in a race for that number one spot and from my point of view, let the race begin."
Boateng added that he was looking forward to his new challenge: "I'm stepping out of my comfort zone at Middlesbrough.
"I've been there for six years and still had a year to go but I think this is a huge challenge and a huge task for the club and the players if we can maintain our Premiership status."
Meanwhile, Halmosi said he was not fazed by the record fee the club have paid for him: "I'm very happy and it's a big chance in my career to play in the Premier League.
"I won't worry about how much Hull have paid, I'm a professional football player, I'll just go out on the pitch and play."
Hull are also currently running the rule over South African international midfielder Delron Buckley and have confirmed they have opened talks with his agent.
Currently on trial at Hull from Borussia Dortmund, he has impressed assistant boss Brian Horton and scored in Tuesday's 4-0 friendly win at Winterton Rangers.
Horton told BBC Radio Humberside: "It's hard to find left-footers, he's sharp, he's bright, he scored a goal [against Winterton] and he's done well in training.
"The manager is going to speak to his agent and his club and we'll see how far we can go down the line."
Hull have also handed a trial to Argentinian keeper Sebastian Cejas, 33, who played in Italy for seven years including three-year spell at Fiorentina.
