Conor McGrandles’ header in the third minute of time added-on early a dramatic point for the Addicks for a 2-2 scoreline on the south coast.
Abu Kamara’s stunning strike and Colby Bishop’s penalty had twice but the Blues in front, before being pegged back, but remain top of League One.
Nonetheless, there were some excellent displays amid the point – and here our our Pompey player ratings...
9. Sammy Silvera - 6
Continues to operate in the 10 and definitely had some good moments, yet faded in the second half as the Blues struggled to keep possession. Regardless, has been an encouraging pre-season. Photo: Jason Brown
10. Josh Murphy - 5
(Replaced by Christian Saydee on 43 mins) Comfortably his quietest outing of pre-season and frustratingly unable to get involved. Ironically his best moment led to a first-half ankle injury during a challenge by defender Kayne Ramsay which was firm, but fair. Still, an injury concern. Photo: Jason Brown
11. Kusini Yengi - 7
(Replaced by Callum Lang on 71 mins) Far better compared to recent friendlies. Had one lovely turn and run in the first half, culminating in driving a shot from outside the box just over. More involved in the first half, holding the ball up and always looking to create. Photo: Jason Brown
