WIMBLEDON — It took Andre Agassi just minutes to send down winners in the BBC studio and make a point of Sir Andy Murray’s critique regarding tennis coverage.

A welcome arrival for the BBC, a late arrival too, Agassi joined Tim Henman and John McEnroe on Friday to preview Novak Djokovic’s Wimbledon semi-final with Jannik Sinner – before then commentating on the match as well.

Henman was the British rose sat between two of tennis’ thornier characters, and the back-and-forth between Agassi and McEnroe – with 17 grand slam singles titles between them – was as engrossing as any encounter this week.

Henman was enjoying it too: after McEnroe eventually declared he had to go – he juggles BBC with ESPN duties at SW19 – he still wanted to hear Agassi’s take on Djokovic versus Sinner, perhaps forgetting he was asking one of the great readers of this sport.

A lengthy, deeply analytical answer followed, and after Henman quipped “is this all you got?”, McEnroe insisted “no, no, I want to hear the end of this”.
