Manager Micky Adams says Brighton must learn to be sharper following their first defeat of pre-season at Withdean.

Chris Dickson's goal saw the Seagulls lose 1-0 at home to Charlton.

And Adams told BBC Southern Counties Radio: "When we get possession we have got to be better with it and more progressive with our passing.

"Some players have done themselves good - others will be disappointed with what they have produced. I was disappointed with one or two."
