After three troubled years with McLaren, Honda concede they need to decide whether they can cope with the “pressure” and “responsibility” of powering Red Bull before entering a possible deal.

Red Bull are considering their options for next season, which include staying with current supplier Renault or swapping to Honda.

But while much of the focus is on what Red Bull want, Honda motorsport boss Masashi Yamamoto says the Japanese company also needs to consider the ramifications of adding Red Bull to their customer list.

They have reportedly already began talks with Red Bull but Christian Horner is adamant he won’t make a decision until he’s seen both engine supplier’s Canadian GP upgrades.
