Manchester United have added a fourth star to their list of 'unsellable' players following Saturday's FA Cup triumph over derby rivals Man City. There are many issues to address at Old Trafford following the end of the season with manager Erik ten Hag's future top of the pile, while recruitment is another top priority. Ten Hag may have secured himself a career lifeline by guiding United to their best performance of the season at Wembley and four of his players are now regarded as untouchable by the club, as reported by the Manchester Evening News. A dreadful Premier League campaign - that saw United suffer their worst-ever finish in the competition - has led to questions being asked over what players will still be at the club next season.
