Fernando Alonso and Stoffel Vandoorne have been limited to short runs as a result, and McLaren are now said to be considering a quick break-up just weeks away from the start of the new campaign.
With such a short timescale to work with, it does appear very unlikely that the duo will part ways so close to Australia as they would also need to secure an agreement with one of the engine suppliers.
A new chassis would also have to be created and Honda provide a big financial boost to McLaren, something that would leave a big gap in their resources.
However, after yet another disastrous start to winter testing which has already left McLaren playing catch-up, it would come as no surprise if this did become the beginning of the end of the three-year partnership.
WOW.I BEG HER WIN
