The Welshman has shown an extra jump in his step as of late, and it has not gone unnoticed among his teammates.
"Craig has been unbelievable," said Kuyt in an interview published in LFC Magazine. "He came late in August and we did not pay a transfer fee."
Bellamy played a key role in pushing the Reds past Manchester City into the Carling Cup final, and has really stepped up his play in recent months.
"He has been a brilliant signing for us and looks even better now than he did the first time he came here," said Kuyt. "It's not very often you can say that about a player who plays for a club in two spells.
"Usually the first time is better but this time, with Craig in better shape, he knows exactly what he can do and he's really professional in training every day, not just helping himself but the whole of the squad."
Belllamy leads LFC in Premier League goals with six, despite playing far fewer minutes than second-place Luis Suarez, who has five.
Bellamy has also performed well in the FA Cup and Carling Cup matches for Liverpool. He is definitely a bright spot in manager Kenny Dalglish's strike-force.
