Borussia Dortmund star Shinji Kagawa says he is watching Liverpool with great interest this season and feels Jurgen Klopp has already made a big impact at the club, the Daily Mail report.
The Japan international was signed by Klopp at Dortmund in 2010, helping the club lift two Bundesliga titles plus the DFB-Pokal cup before moving to Manchester United in the summer of 2012.
Klopp left a lasting impression at Dortmund with the club entirely grateful for his huge achievements.
Kagawa, now back at Dortmund’s Signal Iduna Park, admits still watching his former boss with great interest at Liverpool and already sees a big improvement from the Reds.
“I am interested in how much and how quickly Klopp, the manager that I know, can change the team at Liverpool,” Kagawa said.
“He is a great coach and the results prove it, so I hope it will continue for him and I am interested in how much they can contend as a team this season.”
“Already they drastically changed now and I have read articles that they won eight games in the last 10 games [seven in 11]. I do watch the games sometimes when I have time or when they broadcast on TV.”
Klopp joined Liverpool in early October and the biggest difference during his reign thus far is the increase in intensity and fitness, running on average an extra 6.9km per match.
The Reds have experienced some superb results, beating Chelsea, Manchester City and Southampton on their travels with the latter a 6-1 thrashing in the League Cup quarter-finals.
However, Anfield has yet to become a fortress for Klopp and a big improvement must be made on their home patch in order to have any chance of challenging for the top four this season.
The Merseysiders currently lie in ninth position in the Premier League table, five points shy of fourth.
