Man City's Walker Misses Training Before Champions League Final

Kyle Walker, a Manchester City defender, was absent from training due to a back injury.
Pep Guardiola, Manchester City's manager, said Walker's absence was precautionary.
The rest of Manchester City's first-team players participated in training as usual.
Manchester City is trying to win three major trophies this season, having already won the Premier League and FA Cup.
If Manchester City wins the Champions League, it will be only the second English club to win all three competitions in one season.
