Romain Grosjean is the latest driver tipping McLaren to make real impact in the 2018 Formula One season.
McLaren finished ninth of the 10 teams in 2017, taking just 30 points all year, with Fernando Alonso contributing 17 and Stoffel Vandoorne chipping in with 13.
Reliability issues and a lack of power have dogged the Woking-based marque in recent seasons and they have now ended a three-year partnership with engine supplier Honda.
The team will be taking Renault power units in the 2018 campaign and four-time world champion Lewis Hamilton feels they will be up there challenging for honours once again.
Hass driver Grosjean agrees and sees no reason why McLaren cannot match the pace of the top teams.
"McLaren will be very strong," he told Italy's Autosprint. "They have huge resources and probably the biggest structure in Formula 1.
"The Renault is a respectable engine - they've had reliability problems but in terms of power they are there now.
"The bigger question is about Williams, Force India, us and Toro Rosso with their new power unit. I think McLaren will be there with Red Bull, then there will be Renault."
