Steven Gerrard secured his first Old Firm Derby win as Rangers manager on Saturday as his side recorded their first victory over Celtic in over six years.
The Gers won 1-0 in front of a fevered Ibrox crowd to move level on points with their first-placed rivals.
Ryan Jack's 30th-minute deflected strike proved enough for Gerrard's men, their first victory over Celtic since 2012.
In 2012, the Gers won 4-2 and 3-2 in two meetings with Celtic, though they were also beaten by their rivals twice as they eventually finished second in the SPL.
