One of the key concerns that will always follow a successful or in-form professional sports team is complacency - and this should be a factor very much on the minds of both sides at Twickenham as England prepare to take on Italy.
Stuart Lancaster's men have made an impressive start to their RBS Six Nations campaign - and they will be looking to follow up wins over Scotland, Ireland and France with victory over the Azzurri.
But although a win against Jacque Brunel's side may seem a formality in their quest for a Grand Slam since 2003, the home side will have to proceed with caution.
The vast improvement of Italian rugby - both at club and international level - and the unpredictability of this year's Championship means there can be no guarantees.
Although the Azzurri's overall form is still wildly inconsistent they have shown signs that they can be more than just the competition's whipping boys.
Italy pushed England to the limit last year in Rome, having lead 15-6 at one stage before succumbing to a close 19-15 defeat.
The game, played in tricky conditions, still symbolised the huge progress the Italians had made in a short space of time.
It was a world away from the side that lost 67-7 in 1999 and was hammered 80-23 two years later.
Italy also suffered an embarrassing 59-13 loss at Twickenham in 2011, when Chris Ashton cut loose to score four tries.
But their spirited performance in Rome last year, though, coupled with their excellent opening 23-18 triumph over France at the Stadio Olimpico this season, means England will have to work equally as hard as they did in grinding out results against Ireland and the French.
The return of Sergio Parisse, the talisman of the Azzurri, will also be a massive boost - and will ensure England remain fully focused on the job in hand.
