Pep Guardiola, Manchester City manager, has confirmed that his team will not hold a celebration party for winning the FA Cup due to an upcoming Premier League match against Bournemouth, while also remaining evasive about his own future.

Following the match, Pep commented on his team's performance and celebration plans: "They played much better in the second half. Before Antuan (Semenyo) created chances, then we played better after Antuan scored."

"This is a magnificent trophy. I've done very well this year. Last season was the most difficult for many reasons. As for the celebration, there isn't even a beer. We'll celebrate next Monday after the game against Aston Villa. You know the game against Bournemouth (away on Tuesday) will be even tougher. We'll try to go there and get a good result."

The 55-year-old head coach also sidestepped questions about his own future amid reports that he could leave Manchester City at the end of this season, saying: "You're asking about rumors? What rumors? Let's just enjoy tonight."

Chanthaburi naval forces conducted intensive border patrols and arrested 13 Cambodian workers who admitted to illegally crossing into Thailand to escape poverty and unemployment caused by severe economic collapse in Cambodia, trekking through forests to enter the country.

On May 16, 2025, at 5:30 p.m., military personnel from Unit 526 (Ban Lam) and police from Ban Plaeng station in Chanthaburi jointly apprehended nine Cambodian nationals—five men and four women—who were trekking through forest terrain to illegally enter Thailand in the area of Sector 53, Moo 4, Thep Nimit Subdistrict, Pong Nam Ron District, Chanthaburi Province.

Preliminary investigation revealed that all migrants came from Banteay Meanchey and Prey Veng provinces without travel documents. They entered Thailand illegally because Cambodia offered no employment opportunities and severe economic hardship made survival unbearable. They decided to risk crossing the border hoping to find work in Chanthaburi, Rayong, and Chon Buri provinces.

On the same day, authorities also arrested Mr. Noom, 54 years old, along with four other Cambodian nationals—two men and two women. Noom was driving a pickup truck waiting to pick up the four Cambodian migrants at the forest edge. Investigation revealed that a Cambodian human smuggler had led the migrants through natural passage routes, charging 5,000 baht per person for transport services intended for work in Wang Sombun District, Sa Kaew Province. The smuggler had coordinated with Noom to pick them up at designated coordinates. Authorities have proceeded with legal prosecution.
