Jan Vennegoor of Hesselink could be joined at Hull by more new faces in the coming weeks, manager Phil Brown claims.
Dutch striker Vennegoor of Hesselink today signed a two-year deal with the Tigers to become the club's eighth new arrival since the end of last season.
The 30-year-old was a free agent after leaving Celtic at the end of last season and the deal was therefore not subject to the usual transfer window restrictions.
Hull managed to recruit just Ibrahima Sonko from Stoke on deadline day earlier this week but Brown claims he was not concerned by the lack of activity.
"We've got one or two in the pipeline that are available because they're out of contract for whatever reason," Brown told the club's website, www.hullcityafc.net.
"When the transfer deadline came on Tuesday, we always knew we had one or two irons in the fire after 5pm."
The signing of Vennegoor of Hesselink increases Brown's striking options after a largely frustrating summer in the transfer market.
Potential deals for Michael Owen, Marc-Antoine Fortune, Fraizer Campbell, Bobby Zamora and Daryl Murphy all fell through but Kamel Ghilas from Celta Vigo and Jozy Altidore, on a season-long loan from Villarreal, did sign.
Brown believes the incentive of a possible World Cup place will now give his latest signing the motivation to deliver in the Barclays Premier League.
Brown added: "Where Jan was concerned, there was a contract offer on the table at Celtic, but he felt as if he was better than that.
"He also has a massive point to prove with regards to the Dutch national team.
"He's 30 years old and probably still in his prime in terms of his football career.
"If you look at his goalscoring record, it's almost second to none. It's a one-in-two almost all the way through his career."
The former PSV Eindhoven forward, who spent three years at Parkhead, has been training with FC Twente in recent weeks.
"I looked at other clubs and held talks with them, but I didn't get the right feeling from them," said Vennegoor of Hesselink.
"When I came to Hull City, I got the right feeling straight away. I am glad that everything has worked out okay and I am now looking forward to the challenge of playing in the biggest league in the world.
"I want to play at the next World Cup. If I'm playing club games, that will give me the opportunity to get back into the Dutch squad."
The signing of Vennegoor of Hesselink came on a good day for Hull as goalkeeper Boaz Myhill also committed to a new three-year contract.
The 26-year-old Wales international, who signed from Aston Villa for £50,000 in 2003 and has played for the Tigers in all four professional divisions, is now committed until 2012.
Myhill has re-established himself as the club's first choice after losing his place to Matt Duke for a brief spell midway through last season.
Brown said: "I know Dukey got himself into the first team for six or seven games and that must have surprised Bo at the time, but he has come back stronger.
"I'm delighted to get Bo tied up to a decent contract long term."
Brown added there could be "one or two more announcements in the near future" regarding the contracts of other players.
