Lock Martin Purdy has warned London Welsh must up their intensity when they face Rotherham Titans at Old Deer Park on Saturday.

The former Wasps second row helped the Exiles up to fourth in the Championship table with a hard fought 21-10 win at Plymouth Albion last weekend.

It was Welsh’s third league win of the campaign, but a statistic matched by visitors Rotherham who are only below Phil Greening’s side on points difference.

“Rotherham have started the season fantastically well and are looking very difficult to beat,” said Purdy.

“They have a big pack and they look to come round the fringes and run hard and win those collisions, so if we tackle like we did last week we will lose the game.

“We weren’t really flying in as much we should have been against Plymouth, so that is something we will be looking to remedy this weekend. We will have to up our intensity and physicality.”

Purdy, who won Premiership and Heineken Cup titles with Wasps, joined Welsh from Italian side L’Aquila during the summer, He added: “We haven’t quite put every thing together yet, which is expected as it is a new team.”
