#4 Liverpool - 2008/09
Liverpool achieved this accomplishment in the 2008-09 season. Going unbeaten at home, Liverpool challenged Manchester United for the Premier League right down to the wire. They, however, ended 2nd in the league, 4 points behind the winners.
Other than going unbeaten that season, there was nothing much for the fans to cherish about. The club didn't do well in other competitions. They got knocked out in the 4th round of the FA Cup and the League Cup (currently known as the Carabao Cup). They also lost to Chelsea in the quarter-finals of the Champions League.
The club is yet to go unbeaten at Anfield ever since, and their search for a Premier League trophy also continues.
