What they said...
Saracens head coach Mark McCall...
"London Welsh have been a highly competitive team all season and they bring a high level of intensity and work rate to matches.
"The challenge for us on Sunday, and for the remainder of the season, is to continue to build on our performances and concentrate on our own game plan.
"If we get those things right, we will give ourselves a good chance of getting the outcome that we want."
London Welsh head coach Lyn Jones:
"We were very disappointed with the result and our performance at Exeter last week and we're determined to put that right on Sunday, but it doesn't get any easier against arguably the best team in the Aviva Premiership at the moment.
"However, we're looking forward to visiting Allianz Park and putting on a good show."
