Hull City have £4.5m offer for Celtic striker Gary Hooper rejected That is likely to mean a second offer is made in the next few days, although it remains to be seen whether Hull, who have plenty to do to strengthen their squad in order to survive in the top flight, are willing to spend so much of their budget on a player who will be available on a free transfer in just over 12 months. Norwich, though, have since signed Dutchman Ricky van Wolfswinkel from Sporting Lisbon for £8.5 million and are unlikely to bid for Hooper again. Hooper scored 31 goals in 51 matches, more than any other Englishman, in all competitions last season and was a key member of the Celtic team which reached the knockout stage of the Champions League. Despite his prolific form in Scotland, the 25-year-old has not been selected by England manager Roy Hodgson and his desire to return to the Premier League is partly inspired by a desire to break into the national side ahead of next summer's World Cup Finals in Brazil. Hooper came close to earning his first England call-up for the friendly against Sweden back in November, but missed out because of an injury and has remained on the periphery of the squad ever since.
