On 30 August 2016, Rangers and Hibernian were issued with notices of complaint by the Scottish FA's compliance officer in relation to the Scottish Cup final. The end of May, post the 2016 Scottish Cup Final, saw Rangers continue preparations for the forthcoming season with the signing of English Championship winner Joey Barton from Burnley, Liverpool youth player Jordan Rossiter and former Tottenham Hotspur play-maker Niko Kranjčar. Rangers managing director Stewart Robertson also disclosed Warburton and Weir were negotiating new contracts, with the pair agreeing one-year extensions on 12 July. Warburton would go on to bring in eleven new players in total, including paying a million-pound-plus transfer fee for Englishman Joe Garner which represented the largest investment made by Rangers in a player for over five years since the signing of current club captain Lee Wallace in July 2011.
