It's rare that you see a yellow card in a pre-season friendly, because referees tend to be more lenient with no stakes, but Dominik Szoboszlai bucked the trend in Liverpool's game against Darmstadt on Monday evening.
Szoboszlai went to ground in the opposition half in an attempt to win the ball but mistimed his challenge and brought the man down. After checking his victim was okay, he was greeted with a caution by the match official.
We've already written that he's shown something of a penchant for fouls during Liverpool's pre-season friendly schedule, and this time he was punished for it.

It was, all in all, a mixed showing for the midfielder as he prepares for a likely Premier League debut against Chelsea on Sunday following his $77m (£60m/€70m) from RB Leipzig earlier in the summer.
Not everything he tried came off, and those hoping for a big goalscoring impact after years of limited midfield contributions haven't been given all that much encouragement. Here, he saw an effort from the edge of the box comfortably gathered by the goalkeeper.
But the big positive for Szoboszlai was that he had a hand in two of the Reds' three goals, assisting one of them.
First, his corner in the opening minutes created chaos in the Darmstadt defense, with Virgil van Dijk inadvertently bundling the ball onto Mohamed Salah, who was able to prod home from close range.
He took another just before the hour mark, again on the left-hand side, and this time Luis Díaz was able to meet the ball at the front post and produce an audacious improvised finish.
This wasn't the first glimpse of the threat he poses from corner kicks. In an early friendly against Leicester City, which Liverpool won 4-0, a planned combination with Joël Matip fashioned a goal for Ben Doak.
Jürgen Klopp has been experimenting because he knows that the 22-year-old was a highly effective set-piece taker during his time at Leipzig. Last season, he recorded 31 shot-creating-actions from dead-ball passes, ranking him 10th among all players in the Bundesliga.
And, to focus on corners specifically, he averaged 0.5 key passes per game from these situations in 2022/23, which placed him inside the league's top 15.
All of this gives Klopp something of a dilemma as he assigns the player roles for the trip to Stamford Bridge. Szoboszlai has shown glimpses of a potentially potent weapon, but Klopp also has full-backs Andy Robertson and Trent Alexander-Arnold to think about after watching them produce deadly deliveries for years.
There's then the added complication of January signing Cody Gakpo, who proved himself to be a specialist during his time in the Netherlands and who should not be discounted.
Liverpool led the Premier League for set-piece goals last season on 17 and, with an embarrassment of riches at Klopp's disposal, the Reds look nailed-on to be right up there again this term, with another element of their attack that offers ample excitement.
