Dirk Kuyt is backing fellow Dutchman Ryan Babel to a huge impact during his time at Liverpool.
"The Premiership is one of the best leagues in the world and it is also very physical, so it is normal that Ryan will need more time to show his best.
"But in every game and in every training session he is getting better and better and stronger and stronger.
"It is another level but I am sure he will be at that level very soon."
