"Steven is doing well. The problems we had at the beginning of the season because of the World Cup were clear," said Rafa Benitez.
"The World Cup was a big problem for several players when they returned to their clubs.
"They were not able to do the right training, and that explained why we started our season so slowly.
"Now we have time between matches to train and prepare, that is the reason they are all in a better situation.
"The team is in a very good moment now, we are playing well, scoring goals and maybe some players have more confidence because we are closer to the Champions League semi-final. It is a good moment for them."
