Eric Boullier has denied that Mercedes' dominant form is bad for F1 and adds that rivals need to be patient as they will catch up at some point.
Last year Formula 1 swapped from V8 engines to 1.6-litre turbocharged V6 engines and that heralded in a change of the guard.
Red Bull's Championship run came to a sudden halt while Mercedes came to the fore.
The Brackley team won 16 of the season's 19 races on their way to both Championship titles.
That form has continued into this season, leading to massive criticism from Red Bull's Christian Horner who says it is spoiling the show and needs to be stopped.
Boullier, though, says one team emerging as the dominant force was to be expected given last year's rule changes but he's confident rivals "will" close the gap.
"I don't think it's bad for the sport," the McLaren Racing Director told Sky Sports F1.
"Obviously everybody wants to have all the cars racing together like we had in 2012 or 2013.
"But any technical change, more than sporting change, in the regulations opens the door to create gaps and loopholes. So it's no surprise.
"If you have a good rivalry with Mercedes then you have to be patient. The team will catch up."
