When Jurgen Klopp came in at Liverpool, most of the media and fans were not expecting a dramatic improvement until after the summer because it was Brendan Rodgers' team, but after their positive run of form - particularly in Europe - were the transfers made by the former manager as bad as we all thought?
It's no secret that under Rodgers the fans gave him and their transfer committee a hard time over transfers. They also blamed them for wasting the Luis Suarez and Raheem Sterling money on signings that did not improve the team.
Every manager has poor signings as you can never get it spot on, but Brendan Rodgers was slated for some high profile signings which should have never happened. Some of the money left from the sales of Sterling and Suarez was wasted and spent badly on a risky transfer of Mario Balotelli and former Southampton legend, Rickie Lambert.

However, other transfers that critics thought were a waste of time and money included Dejan Lovren, Adam Lallana, Emre Can, Mamadou Sakho and James Milner.
Huge improvement under Jurgen Klopp
All the players mentioned above have become key players for Liverpool since the arrival of Klopp and one player has stood out as going through the biggest transformation - Dejan Lovren.
After a poor first season under Brendan Rodgers, Liverpool fans thought he was one of the worst signings in years and not just because of his £20 million fee - he was simply not good enough.
With Martin Skrtel in poor form and Sakho suspended, Lovren has become the main man at the back and has potentially saved Liverpool's season with key tackles and vital goals, including the last-minute winner against Borussia Dortmund.
The latter four were not given as much stick as the Croatian, but they did get their fair share from Liverpool fans.
Adam Lallana did not look like the player Liverpool paid over £25 million for as he had made a solid but unspectacular start, although injuries certainly did not help the former Southampton captain. Under Klopp, he's been involved in most of Liverpool's goals this season and plays a major part in Liverpool's front three also including Philippe Coutinho and Roberto Firmino.
Emre Can's youth was an excuse used by most Liverpool fans, but being played at centre-back by Brendan Rodgers made him look lost at times and developed a tendency to overplay the ball. However, since moving back into midfield, he's become a very promising player for the Reds.
Mamadou Sakho looked like Bambi on ice most of the time at the back, as his distribution was poor and he frequently missed the ball. Alongside Lovren, Sakho has developed into a key player at the back with his passion and determination, but with his failed drugs test he could be facing the axe as a Liverpool player.
James Milner came on a free transfer from Manchester City with a wealth of experience but his use of the ball and deliveries were poor, particularly from corners. He simply looked a shadow of the player who had won the Premier League title twice with his former side. More recently, Milner has stepped up into a captain's role, improving his set-piece delivery and really becoming the creative force Liverpool thought they were getting last summer.
The five players had a combined transfer fee in the region of around £80 million.
But now under Jurgen Klopp, it looks like money well spent. They have all been playing exceptionally well and everyone can agree it can't be any coincidence that the German's man management skills and knowledge of how to get the best out of people have come to the fore once again.
The thing that excites Liverpool fans has to be the huge improvement in such a short space of time, which many feel will see the Reds back to their true best in the league next season. They say 'you can't polish a turd', but Jurgen Klopp has done just that.
