McManaman reckons Klopp needs two summer transfer windows to turn things around at Anfield despite a good start to his Kop career.
And he believes Euro 2016 represents the German’s best chance of finding the kind of star Liverpool have missed since Luis Suarez left.
Klopp has already taken the Reds into a Capital One Cup final, and his team are chasing down the top four in the Premier League.
They also have a 2-0 lead over Manchester United ahead of Thursday’s Europa League last 16 second-leg clash at Old Trafford.
But McManaman claims Klopp cannot be judged properly until he’s had two summer windows to work his magic, starting with a big one this June.
