London Scottish warmed-up for today’s exiles derby clash with London Welsh with what head coach Peter Richards described as the best win in his time at the club.

Scottish turned over unbeaten and table-topping Yorkshire Carnegie 30-27 last week, thanks to Peter Lydon’s last minute penalty at Headingley.

The result moved Richards’ men up to third in the Championship table and welcome fourth-placed London Welsh to the Athletic Ground.

And the head coach is confident a repeat of last week’s performance will put his side in the running for a fourth straight win.

“it’s our second London derby of the season and we’re all looking forward to it.” said Richards.

“They are on a good run winning games and we know that it will be very difficult.

“But we’ll prepare the team as best we can and we know that if we play like we did last weekend that we’ll be very hard to stop.”

Lydon scored a try and kicked 15 points in a fine Scottish effort that also featured tries for Drew Locke and number eight Mark Bright, who was celebrating his 100th appearance for the exiles.

Meanwhile, head coach Rowland Phillips has warned his London Welsh men they can ill afford to be wasteful when they face the Scots.

Phillips' side led Bedford Blues 19-3 at Old Deer Park on Saturday, but needed a try-saving tackle from Rob Lewis to secure a 30-24 win.

Phillips is mindful the Scots have found their form after an opening day defeat to Moseley and wants Welsh to take their chances or risk defeat to their neighbours.

“We’ve got to start learning very quickly as a team because you’re not going to get away with that every time. It will come back to bite you,” he said.

“We scored 30, but left a lot more points out there. We’ve got to be able to take these opportunities.”
