A true Liverpool stalwart in every sense, Scottish defender Mackinlay enjoyed one of the longest careers of any Liverpool player, making his debut as an 18-year-old in 1910 and playing his final game 18 years later.
A losing finalist in the 1914 FA Cup final, he recovered from that disappointment in style by skippering the Reds to successive league titles in 1922 and 1923.
Regarded as an uncompromising, hard-tackling defender, Mackinlay was predominantly used as a left-back but displayed such great versatility that he could also operate at wing-half, centre-half and right across the forward line.
Long before the term “overlapping” had become part of football parlance he was a great exponent of the art, his speed carrying him menacingly into the opposition penalty area.
A consistent performer during the course of his lengthy stay at Anfield he finally bowed out having made 433 appearances.
