Manchester United manager Jose Mourinho has said there will be times when he needs to adopt a more pragmatic approach despite the free-scoring start that sees United top of the Premier League.
Marcus Rashford scored the opener three minutes after coming on and Jesse Lingard and Marouane Fellaini combined for the second goal to complete United's third straight win of the Premier League season.
"We played very well", Mourinho, whose side are yet to concede a league goal, said to BT Sport.
"I saw the ball jumping in the net, or the guys jumping, I don't know". He's complaining about an ankle problem, so he's the kind of player where we need to have him always in our hands with a lot of care from the medical department, from the fitness coach, from my assistants, on the gym working always on prevention, on recovering. Maybe they say I'm defensive.
Sir Alex Ferguson once claimed the centre-back could become the club's greatest-ever player, while Sir Bobby Charlton is among those to have previously compared Jones to the late, great Duncan Edwards.
Mourinho attributes United racing out of the blocks to the work they did during their pre-season tour of the United States, where Manchester City, Real Madrid and Barcelona were among their opponents.
Shakespeare's hope now is that all of his players will be returning after an worldwide break which also sees the transfer window's closure, with Danny Drinkwater, Jamie Vardy and Riyad Mahrez having all been seen in the gossip columns recently.
"Were Leicester very risky against Arsenal?" Were they unsafe against us?
"We had a very good pre-season. So I think now my team is also the mirror of the work we are doing in clean weeks where we can train five days and go through every item of the game plan". "We worked really well, had great conditions, to work together 24 hours per day in a lovely atmosphere in Los Angeles".
"The difference is the quality of our football, we're playing better now and if we hadn't won this match I wouldn't have anyone to blame".
