Potential McLaren Partners for ‘JB’ if Fernando Alonso Retires

Kevin Magnussen

The Dane was Button’s teammate in 2014, and drove in the 2015 Australian GP as Alonso recovered from that testing crash in Barcelona before the season started. Magnussen is arguably the most obvious choice, but with rumours going around that he will be joining the new Haas F1 team alongside Romain Grosjean, McLaren may not have him as an potion for much longer.
