Jurgen Klopp says Mohamed Salah "has made a big step this season" after his double against Huddersfield lifted him into pole position for the Golden Boot.Salah won the award with 32 goals last season but Klopp believes "it is a bigger achievement" for the Egyptian to be leading the way again."It's such an important year for him after a campaign where every shot was a goal last season," Klopp told the BBC."He is being really assessed by people to see if it was a one off."Salah's 21st league goal of the campaign saw him take the record for the most goals scored (69) by a Liverpool player in his first 100 games for the club.The Egyptian also moved ahead of team-mate Sadio Mane - who also scored twice against the Terriers - in the race for the Golden Boot when he slid his second goal past Jonas Lossl late on."He looked like he wanted to break that record tonight because after the second goal it was like 'me against the rest of the world'," added Klopp."Thankfully all of the others are doing that as well and that is why we are in the situation we are in."Salah has become only the third Liverpool player to score more than 20 Premier League goals in consecutive seasons for the club, after Robbie Fowler (1994-95 and 1995-96) and Luis Suarez (2012-13 and 2013-14) also achieved the feat.Victory for Liverpool saw them move back to the top of the Premier League on 91 points, with a two-point advantage over Manchester City, although the defending champions have one game in hand."We have to do our job and win the games," Klopp told Sky Sports. "To have 91 points is incredible and we should mark that day because it doesn't happen every year."The boys have done everything possible to give ourselves a chance."
