Pompey lost to Charlton Athletic this week by a 3-0 scoreline, extending their winless League One run to four games.
Two of the goals scored by Charlton were from set-pieces, with the first one resulting from a corner and the second one from a free kick, with Portsmouth letting the Addicks’ players get away with headers from close range.
Robertson recognises that set-pieces are a problem for Portsmouth and thinks that sorting that particular issue out is necessary for his team to make progress.
In general, the Portsmouth star thinks the team as a whole need to be defending better and took the blame for the third goal conceded.
“We can’t keep conceding from set-pieces in this league – it’s happened too often this season already”, Robertson was quoted as saying by Portsmouth’s official site post-match.
“So we need to sort that out quickly because if you don’t get them right at both ends of the pitch, you’re not going to win games.
“We have a big team and have to be defending them a lot better.
“I hold my hands up for the third goal because it was a free header.
“Our response to going behind was poor and we didn’t recover well enough.
“We didn’t get going at all and were miles off.”
Portsmouth next take on Forest Green Rovers and they will be looking to make a comeback against a team that have conceded 31 goals already this season.
