Liverpool have beaten arch-rivals Manchester United and thumped big spending Tottenham Hotspur this season, but manager Brendan Rodgers believed Wednesday’s 2-0 success over Hull City was their best of the campaign.Daniel Agger’s 36th minute header and Luis Suarez’s peach of a free-kick five minutes after halftime secured all three points for Rodgers’ side, who had lost their last two English Premier League matches 2-1 away at Manchester City and Chelsea.The victory, against a Hull side that trounced relegation candidates Fulham 6-0 last time out, moved them up to fourth in the table and earned high praise from the Northern Irishman who also welcomed back captain Steven Gerrard after injury."I said to the players afterwards that I thought that was our best win of the season,” Rodgers told reporters.  "In a lot of games we’ve been vibrant and had great energy, scored goals and performed well, as well as won games."But on the back of the games that we’ve had over this period and to play with a lot of the same players against a team that won their last Barclays Premier League game 6-0, we knew that we were going to have to tough it out today and dig in.Liverpool moved top of the table at Christmas after they followed up the 5-0 win over Spurs with a 3-1 success at home to Cardiff City but they have fallen six points back of leaders Arsenal after back-to-back away defeats.Suarez failed to score in the two losses to City and Chelsea but notched his 20th this season on Wednesday to cement his place at the top of leading goalscorers’ chart.
