The Tottenham centre-back has been discussing his side's 2-1 loss to Newcastle United on Sunday afternoon.
It's usually the Magpies faithful booing their team after a Premier League game but Newcastle sealed back-to-back wins after coming back to beat Tottenham 2-1 at Whit Hart Lane.
And some home fans booed at full-time - something Vertonghen can accept.
The Belgian is quoted as saying by the Standard: "It was just disappointment. We were disappointed and they were as well. I can understand that."
One might suggest booing only a second Premier League defeat of the season is harsh - but it really is understandable from Spurs fans.
It's the same old story every season from Tottenham in that the games you need to win if you want to reach the top four simply aren't being won.
That's the danger of title talk. A good run of form and hysteria begins. Once that hysteria starts, disappointment inevitably strikes.
Tottenham, of course, were hindered by Europa League fatigue once again, having thrashed Monaco with a very encouraging performance indeed on Thursday night. But few can blame supporters for being frustrated, especially after Mauricio Pochettino's side led for the majority of the game on Sunday afternoon.
