Two-time British and Irish Lion Grewcock earned his corn for being just that, the second-row comfortable doing the ugly, unseen work that creates the platform for others to grab the headlines.

And in Botha he believes England have, belatedly, unearthed a gem.  Botha has started, and won plaudits in, all three of England’s Six Nations games as interim coach Stuart Lancaster looks to draw a line under their World Cup debacle, on and off the field.

And Grewcock believes the South African-born lock’s displays will be far from a flash in the pan.

“He might not show the most finesse in the England second row but he offers so much in terms of the dirty work that a lock has to do,” said Grewcock.

“He is someone who has definitely earned their right to be in the Saracens team and now the England team and the early impressions that he has given is that he is here to stay.

“He is a strong runner and a big tackler and I see people are already calling him England’s enforcer which is a testament to the start he is made in an England shirt.

“When you look back at the best teams that England have had then there has always been someone who has been the enforcer – your Neil Back types etc.

“And although it is only early days Mouritz has taken that mantle on himself and he deserves that tag right now.”

Botha’s route to the top of the rugby tree has been a circuitous one to say the least with spells at Bedford Blues and Bedford Athletic, where he combined his rugby with a job in waste management,  before joining Saracens.

And Grewcock believes his long wait for international honours will make the Sarries lock hungrier than ever to stay at the top level.

“He looks like he is making up for lost time because his route to international rugby wasn’t exactly the smoothest one,” added Grewcock.

“Mouritz is someone who has been playing in the National Leagues only a few seasons ago and has really hard to work hard to get where he is now.

“He has been a very strong performer this Six Nations and hopefully he can keep his good first impression up.”
