Mako Vunipola expects "intense" Harlequins clash

Saracens prop Mako Vunipola has claimed that Sunday's table-topping clash with Harlequins in the Aviva Premiership will be "intense".

First-placed Sarries host second-placed Quins at the Allianz Park with four points separating the sides in the table.

"It is a big game between the top of the table sides so it will be intense," Vunipola told Sky Sports News.

"It is a big challenge but it is one we are looking forward to."

Saracens ran out 18-16 winners when the teams met at Twickenham Stoop back in September.
