Celtic began their warm-up for the new season with a gentle 7-0 win over an amateur select in Sweden and a further hint of a change in tactics.
Henrik Larsson's appearance delighted the Swedish fans
Stanislav Varga, Steve Guppy and Chris Sutton put the Scottish outfit ahead before the break against a team combining players from the Kungshamn and Smogen clubs.
Stilian Petrov added the fourth with a penalty before David Fernandez scored a double either side of a strike by young Ross Wallace.
The match at Kunghshamn Vallen Stadium was missed by manager Martin O'Neill.
He was not due at their Kungsbacka training camp until the evening following what Celtic describe as a "minor operation".
But there appeared to be confirmation of summer speculation suggesting that the Northern Irishman is contemplating scrapping his tried and trusted 3-5-2 system.
Stephen Crainey, who has been looking for a new club, started at left-back, with Jackie McNamara on the right, in a more traditional 4-4-2.
Magnus Hedman started in goal and was given a warm welcome by the crowd of 4,700 along with compatriot Henrik Larsson as he partnered Sutton up front.
There was also a welcome return after the break for forgotten goalkeeper Barry-John Corr.
The 22-year-old had been sidelined for two years with a debilitating back injury.
