Returning to McLaren in 2015, Alonso was away from the podium struggle on the British team, which had problems with the Honda engine in the last three years.
This year the team is using Red Bull's renowned Renault engine, hoping the team will be in a podium struggle before the season.
Up to now, three races have been left behind and McLaren has generally shot the fifth best team.
This performance of McLaren, behind Mercedes, Ferrari and Red Bull, was alleged to have given Alonso patience and to leave the team at the end of 2018.
According to the Diario Goal, the Spanish driver is looking at the empty seats in Mercedes and Ferrari, but both teams do not want Alonso because he has champions like Lewis Hamilton and Sebastian Vettel.
It seemed like Renault was the biggest option for the Spanish pilot, but claimed he could retire from F1 at the end of the season if he could not get his bid.
McLaren's contract with Alonso and Stoffel Vandoorne has a one-year option. While Vandoorne was expected to remain in the squad, it was claimed that Alonso would be replaced by Lando Norris, whose name was called Red Bull and Mercedes.
At the moment, Norris, who makes the team's substitute pilot, is commenting on the team that the Lewis Hamilton effect can be made.
