South Korea's K League said that it feels disappointed and cheated by Juventus over the Serie A club's refusal to apologise for forward Cristiano Ronaldo sitting out a pre-season friendly in Seoul last week. Ronaldo was contracted to play at least 45 minutes against the K League All Stars, according to event organisers, but was advised to rest by Juve's medical staff due to "muscle fatigue" from a match played 48 hours earlier in Nanjing.
