Rosslyn Park travel to Blackheath this weekend knowing their attack will need to be on point if they are to cause their London rivals any problems.

Blackheath under head coach James Shanahan have the best defence in National League One, most notably showcased in their 15-0 victory over hotly tipped Darlington Mowden Park.

And it was DMP who scored a last gasp try against Park on Saturday to snatch a 34-33 victory.

“DMP was tough,” said Park Head of Rugby Donnie Masters.

“We went 19-0 up and should have controlled the game better than we did. We gave them a couple of very soft tries and they are too good of a team to be that charitable to.

“It’s frustrating to have scored five tries and not win the game but credit to DMP for going hard to the end and taking the spoils.”

Both teams have three wins in five, but Parks four bonus points have them sixth in the league to Blackheath’s ninth.

Last season Park lost at home and could only draw away, and Master’s is all too aware of what to expect from Saturday’s visit to Well Hall.

“Blackheath away will be tough. It always has been a tough place to go and always will be. A good old London derby with no quarter given. They have an excellent defensive record this season and we will need to play very well to get anything out of the game.”

Both teams are coming in to the fixture on the back of defeats, with ‘heath being left disappointed in how they let a winning position slip away twice at Ampthill & District before their 33-22 defeat.
