His team had just lost 1-3 in the Barclays Asia Trophy final to English Premier League (EPL) rivals Arsenal, but it was another London club that annoyed Everton manager Roberto Martinez after the final whistle.
The burning question after the match to the Spaniard was on the reported £20 million (S$43 million) bid from reigning champions Chelsea for defender John Stones which was rejected by the Toffees.
And when a journalist suggested to Martinez that the Blues are coming back with a £30 million bid, the Everton manager sounded agitated in his reply.
"It is a disappointment to see a club make comments about our player. That is not how we would do it," blasted Martinez.
"We don't comment to the press on players that are registered with other clubs."
Stones stepped in for the Toffees last season when he earned a starting place in favour of veteran defender Sylvain Distin.
The 21-year-old's performances earned him a call-up to the England national team, and he made his competitive debut in the Three Lions' 2-0 away win over Switzerland in the Euro 2016 qualifiers.
Martinez said: "Stones is our player and we are not a selling club in that respect."
Earlier this week, Stones revealed to The Straits Times his intentions to stay and build a cohesive defensive partnership with fellow centre-back Phil Jagielka.
