Norway’s team doctor has dismissed reports of a sickness bug sweeping through the squad ahead of Saturday’s World Cup quarter-final against England.Stale Solbakken’s side have emerged as one of the surprise packages of the tournament and will take on Thomas Tuchel’s men in Miami seeking a place in the last four.Speculation over the squad’s fitness surfaced after several players and staff were affected by illness during the competition, raising concerns before one of the biggest matches in Norwegian football history.Crystal Palace striker Jorgen Strand Larsen missed training before Norway’s opening World Cup fixture after falling ill, while Solbakken was also seen coughing during a press conference earlier in the tournament.The Norway manager admitted there had been “some coughing and rasping” within the travelling party, attributing it to the demands of constant travel, air conditioning and weeks spent together in close quarters.Those comments fuelled suggestions that illness could become a problem before the clash with England.However, team doctor Ola Sand has insisted there is no cause for concern.Speaking to Nettavisen, Sand said: “All players are healthy now.Norway’s team doctor has dismissed reports of a sickness bug sweeping through the squad ahead of Saturday’s World Cup quarter-final against England | GETTY”Very little fuss considering that we have been close together for almost six weeks.”So great that [English media] believe this.
