Fernando Alonso believes that if the 'logical solutions' currently planned by McLaren reach their intended purpose, the team's 2016 campaign will see a significant boost to its fortunes.

The iconic Formula 1 outfit endured the worst season in its history in 2015 as partner Honda struggled endlessly with its power unit troubles.

But with problems now identified and solutions in place, Alonso says the coming year will result in big gains for both engine and chassis which will put McLaren firmly back on the F1 map.

"If we apply some of the solutions and everything is working as we expect, the lap time benefit will be very big," the Spaniard Autosport.

"There are solutions in place which are logical and quite good and keep the motivation very high because I think 2016 will be a completely different picture."

Alonso recently said that a two-second gain was in the cards, and he reiterated his opinion.

"Everyone will improve between 0.5s and one second. With us being two seconds off the pace, we need to do more than 0.5s or one second. I think it will be relatively more than that."
