Alexander Isak trains with Sweden, a day after his mega move to Liverpool

In New York, Carlos Alcaraz produced another brilliant performance to beat Jiri Lehecka and reach the US Open semi-finals (6-4, 6-2, 6-2). He has reached the last four of a Grand Slam without dropping a set for the first time in his career. He's the youngest man to do so since Rafael Nadal at the 2008 French Open.

In the women's draw, Jessica Pegula will face Aryna Sabalenka in the semi-finals, a repeat of last year's final.
