F1: 5 Driver battles to watch in 2019

#3 Carlos Sainz Jr vs Lando Norris

Who will be number one at McLaren?

Just when we thought Red Bull were going through a new era try and compare that to the new generation at McLaren.

Carlos Sainz Jr and Lando Norris are McLaren's hopefuls for 2019 with hardly any outsiders showing any knowledge of how the Woking team will do in the new season.

Sainz comes in for his close friend and fellow Spaniard, Fernando Alonso, while Norris will make his debut season in F1 after competing in Formula 2.

The new partnership could be seen similar to Alonso and Hamilton's partnership that hit thunder and lightning in 2007.

It ended up with Alonso leaving the team after just one season and Hamilton staying on at McLaren to go and win the drivers' championship 12 months later.

Will that be something for Sainz to keep an eye on? With Norris being a driver promoted from the McLaren programme, many will expect Norris to receive a better treatment out of the two.

But who knows how the team will approach 2019.
