Harlequins may have a 100 per cent Premiership record of three bonus-points wins from three games, but winger Ugo Monye has warned the champions are some way off their best form.

Monye scored his third try in two appearances as Quins beat Sale Shakes 37-14 at the Stoop on Saturday to retain their spot at the top of the table.

Director of rugby Conor O'Shea's men face Leicester Tigers at Welford Road on Saturday in a repeat of May's Premiership final triumph at Twickenham stadium.

And Monye reckoned the beaten finalists could get another rude awakening on home turf as they did in October last year.

"We haven't actually played that well, but we have been able to dip in to the strength of squad and the talent on the field we have needed to," he said.

"Despite winning our games we haven't been happy with the way we have played.

"We've nto really played well enough so far and we are going to need to improve.  It is a massive test for us this week.

"It is the start of a tough run of games with Leicester , Saracens, Exeter, Biarritz and Connacht all coming up.

"It is going to be a busy five weeks and we are going to have to be at our best."
