(Reuters) - Liverpool will soon see the best of "world-class" midfielder Thiago Alcantara after a serious knee injury and COVID-19 interrupted his first year at the Premier League club, manager Juergen Klopp said.

It has been a year to the day since Thiago arrived at Liverpool from Bayern Munich in a reported 20 million pound ($27.5 million) deal, with the Spanish international playing 34 games in all competitions, including 24 league games last season.
