Mikael Lustig, the Celtic and Sweden defender, advised John Guidetti to put an end to the grandstanding before the striker agreed a loan move to Glasgow from Manchester City.

Lustig believes his compatriot has benefitted from that advice, since he has scored nine times in 10 matches. "I told him: don't talk as much," said Lustig. "He's started to find his feet and he's beginning to talk again!"
