Horner hails Mercedes start
Red Bull team boss Christian Horner cannot see beyond Mercedes for the Constructors' title after their dominant start to the campaign.
Mercedes drivers Lewis Hamilton and Valtteri Bottas have taken the chequered flag in all five races this term, with Hamilton winning three and Bottas two.
The Silver Arrows have managed a one-two finish in all races so far in 2019 to leave them well clear at the top of the Constructors' table.
Horner doubts that Mercedes can dominate as much as McLaren did in 1988 when they won all but one race but he has been impressed with their start.
"I think it's very much a Mercedes championship, you can see after five races they are three points off a maximum score," Horner told F1 news.
"It's still a long year and we take things race-by-race. They had a really dominant performance.
"They're always strong in Barcelona but certainly their fifth one-two finish is exceedingly dominant."
