The Dane joined Rangers in the summer of 2000 when he signed for Dick Advocaat, making his debut against Dunfermline Athletic on 19th August 2000 but appearing only intermittently when the Dutchman was in charge.
It was under Alex McLeish that Peter began to establish himself as a first team player, his last minute winner against Celtic in the 2002 Scottish Cup Final ensuring hero status in the eyes of the Rangers support. During that 2001/02 campaign, five of Peter's seven goals came in Old Firm clashes and whilst there were question marks over his consistency, he was beginning to demonstrate that he was a player for the big occasion. The blistering pace of Lovenkrands, Neil McCann and veteran Claudio Caniggia in the Rangers forward line appeared to be the preferred tactic of McLeish when facing Celtic.
A further Old Firm goal came in the League Cup Final victory over Celtic in 2002/03 as Rangers took a giant step towards securing an extraordinary domestic treble.
During his time in Scotland, Peter was joined by his brother Thomas who played for St. Johnstone.
It was Peter’s goal against Inter Milan at Ibrox on 6th December 2005 that secured qualification from the Champions League Group stages, the first time a Scottish Club had managed to achieve this particular feat.
Primarily deployed as a left winger during his time at Ibrox, he would enjoy a sustained period of playing as the main striker during his final season at Rangers. Netting 18 goals, this included an impressive run of 10 goals in just 8 matches. With his Rangers contract coming to an end, it was the perfect time for Lovenkrands to find form. Despite ongoing talks, Peter decided his future lay elsewhere and signed for German side Schalke 04 before returning to the UK with Newcastle United.
Peter would later have a brief spell back at Ibrox, working as an Academy Coach at the Rangers Training Centre.
