Brooklyn Nets superstar Kevin Durant said he and his team-mates are focused in pursuit of the Eastern Conference top seed as head coach Steve Nash awaits the return of former MVP James Harden.

Durant posted 42 points and 10 rebounds while matching a career high with seven three-pointers, but the star-studded Nets still lost on Sunday, upstaged 117-114 by Eastern Conference rivals the Milwaukee Bucks, who were fuelled by Giannis Antetokounmpo's 49 points.

The Nets – eyeing their maiden NBA championship – dropped down to second in the east, behind the Philadelphia 76ers but the two title contenders are set to continue going head-to-head for the number one seed ahead of the playoffs.

After falling short against two-time reigning MVP Antetokounmpo and the Bucks in Milwaukee, two-time champion Durant – who scored 42 points in back-to-back games – told reporters: "Every day you wake up, it should be about your craft. I think that's how everybody approaches this thing.

"We try to take it a day at a time, a possession at a time. We can't control what's going to happen at the end of the season or what other teams are going to do.

"I think we've just got to take advantage of each one and that's what we're doing. Guys are locked in. We're talking the game when we're at practice, on the bus, we talk about it on the plane.

"So I think that helps as well. We're staying locked in mentally too when we do it."

The Nets were once again without superstar Harden, who remains sidelined due to a hamstring injury.

Harden has not played since leaving the matchup against the New York Knicks on April 5, missing 16 of the Nets' last 17 games.

This season, Harden – who arrived in a blockbuster trade from the Houston Rockets in January – is averaging 25.2 points, 10.9 assists and 8.0 rebounds per game.

The Nets and Bucks will clash again on Tuesday, and coach Nash said: "I'm not so much worried about what they know. For us, we have the luxury of talent. We have great players. We don't have the luxury of time. That's OK. We understand that and we'll work around that.

"James will give us a totally different dimension, but we don't sit here and say, 'well, wait 'til James gets back'. We try to solve the puzzle now. James will give us obviously something great to build on, but we can look at all the things that we did wrong today and there were a lot of things where I thought we just weren't sharp tonight. We clean some of those things up, I think we give ourselves a better chance."
