The two-time Asian Tour winner has been in focus since his tied 31st place finish. His performance included a stunning hole in one.
Lahiri, who tees up at the picturesque Crans-sur-Sierre Golf Club, said, "The British Open was a great confidence week as you get to play amongst the best and it helps to give yourself lots of self-belief. I think I need to build on that now. I'm always trying my best out there and this week would be a good week to put in a great performance," added the 25-year-old.
Lahiri, sixth on the Asian Tour Order of Merit, has already enjoyed four top-10 finishes including his second Asian Tour win on home soil earlier in the year.
"It's always the second half of the year that decides the fate for most of us. The guys who are looking at making the cut, the guys hoping to win the Order of Merit or getting into top-five or top-10," said Lahiri.
It's a great time of the year to find form and play well. I'm just hoping I get off to a good start and gain some confidence at the beginning of the second half season and keep it going for the remaining half of the year," added Lahiri.
Other notable Asian Tour stars expected to mount a strong challenge at the European Masters include 13-time Asian Tour winner Thaworn Wiratchant from Thailand, Korean-American rookie David Lipsky and South Africa
