RAFAEL BENITEZ has warned Manchester United and Chelsea that Liverpool will improve in the second half of the season, although he admits that even one mistake "can be massive" in his club's quest for a first league title in 19 years.The Premier League leaders' nerve and inexperience at the summit were questioned by United's manager, Alex Ferguson, this week and the Chelsea midfielder Frank Lampard said both Liverpool and United had failed to capitalise on the Blues' run of two wins from seven league games.
Benitez, however, believes that his team, who have lost only one game this season, are yet to realise their full potential. "I believe we can still improve," said the Liverpool manager, who is expected to return to the dugout at Stoke on Saturday after a recent kidney-stones operation.
