"Italy have some very good players and also a very experienced coaching staff, so we know they'll be very well prepared", said Borthwick.
Jones added: "It was always going to be a tough game".
England were too easily carved open out wide for two Italy tries but as well as his defence, Jones will also be sweating on the fitness of Ben Youngs. "We want him to hit the line hard, that's what he's good at".
"We want consistency [from referees] and our maul defence was penalised when theirs wasn't". Jones was having none of it, but it can not be denied that the most eye-catching performance of this ultimately predictable victory - England's self-styled hunters eventually feasting on their Italian prey - was that of Sam Simmonds, the newest member of this side.
Slow starts are a hallmark of this England side and, while that may seem the wrong way to describe a half that began with Watson's tries, it was not looking like the kind of statement the coach had wanted until Italy's young bucks, full of invention and energy, ran out of puff.
Ireland have only beaten Les Bleus in the Six Nations twice in Paris (in 2000 and 2014) and lost two of their three away games in the tournament a year ago.
Only handed his tournament debut in the absence of injured duo Billy Vunipola and Nathan Hughes, Simmonds was one of England's hardest workers, weighing in with 23 tackles, 14 carries and 80 metres made in addition to his two tries.

And while all eyes this weekend will be on the Six Nations, Moody claims the key barometer to England's 2019 World Cup chances lies in the autumn when they face world champions New Zealand. And that all starts on Sunday.
Italy have been whitewashed in seven of their 18 Six Nations campaigns, including each of the last two.
There was to be no repeat this time around and England raced into an early lead as some slick passing following a lineout on the left deep in Italy's 22 saw the ball reach Watson, who turned over in the far corner.
Italy full-back Matteo Minozzi and back row pair Sebastian Negri and Renato Giammarioli will all make their Six Nations debuts on Sunday.
"I said before the game I wanted the young players to go out and show there's a real change in what we're doing as a country", the former Ireland fullback added.
Italy wilted in the closing stages after putting so much effort in and fit-again replacement Nowell helped himself to a seventh try three minutes from time, Farrell failing to convert but England finishing the contest in style with a clash against Wales to come next Saturday.
"It will be another statistic in the book but anyone here today could see what we were trying to do".
