Patrick Roberts scored against his parent club as Manchester City drew 1-1 with Celtic in the Champions League on Tuesday.
The final positions had already been decided in Group C, with City qualifying second behind Barcelona and Celtic finishing bottom.
City manager Pep Guardiola will, however, have been keen to bounce back from Saturday’s 3-1 Premier League defeat to Chelsea and a 3-3 draw in Glasgow earlier in the season that started a six-game winless run in all competitions for his side.
But it was one of City’s own who put Guardiola’s men on the back foot inside four minutes at the Etihad Stadium, Roberts – on an 18-month loan at Celtic – capping a determined run with a powerful finish.
Another City youngster – this time wearing the blue of the hosts – soon levelled, Kelechi Iheanacho rounding off a swift counter-attacking move.
The pace of the game started to reflect its dead-rubber status as it wore on and Nolito’s rightly-disallowed goal was as close as either side came to snatching a winner in the second half.
With nothing riding on the match, Guardiola used the opportunity to give some of his fringe players game time, while 16-year-old Phil Foden was an unused substitute.
But there was to be no winner and Brendan Rodgers will no doubt be the happier of the two managers, with Celtic avoiding defeat on their travels for just the fourth time in Champions League history.
