Piers Morgan has delivered a nine-word response after seeing the Switzerland women's team lose 7-1 to an under-15 boys side.
Switzerland are currently preparing to host the Women's Euros, which will begin on July 2.
The Swiss have been drawn in the same group as Iceland, Finland and Norway.
On paper, the group looks manageable for the Swiss, but their preparation ahead of the tournament has been far from ideal.

Pia Sundhage's side recently lost 7-1 to FC Luzern's U-15 boys team, having previously been beaten 2-1 by FC Soloturn's junior men's team.
FC Luzern currently play in the Swiss Super League and have produced stars such as Haris Seferovic and Jonas Omlin.
In response to Switzerland's defeat, TV host and Arsenal fan Morgan wrote on social media: "This is why we separate the sexes in sport…"
Speaking after the result, Swiss player Leila Wandeler said, via Aargauer Zeitung: "The training sessions are exhausting. But we all want to be in our best shape for this European Championship. That's why I think it's a good thing.
"The result didn't matter. For us, it was about testing our game principles."
Meanwhile, media outlets in Switzerland have played down the result and slammed fans who criticised the team.
Blick said: "Many are astonished and rub their eyes. Especially those who have barely ever been involved with women's football, let alone been around the national team.
"But it's a result that serves as grist to the mill for all those who have always been critical of women's football and who fundamentally lack understanding for the current hype surrounding the European Championship.
"The significance of this result is zero. Because it has no relevance in light of the European Championship, which begins in a week and in which only women compete – because women's and men's football are two different sports."
Another publication, 20 Minuten, added: "Scientifically proven, women have a very difficult time against men in football."
The Swiss are back in action on Thursday evening when they take on Czechia in a friendly match.
