Sunderland midfielder Jordan Henderson has dismissed suggestions that he needs to be rested after an extended run in Steve Bruce's side.The 19-year-old has made 19 appearances for the Black Cats this season but has recently come in for criticism from some sections of the club's supporters. [LNB]"I don't feel I need a rest," Henderson told BBC Newcastle. [LNB]"Tiredness is more a mental thing but I just think I've not played as well over the last couple of games." [LNB]He added: "I just need to keep focused and keep doing what I've been doing before."[LNB] [LNB][LNB] Henderson has been drafted in to partner Albania international Lorik Cana at the heart of the Sunderland midfield following a knee injury to Lee Cattermole. [LNB]And he hopes that his rise from the North East club's academy could be an inspiration to other young players hoping to graduate to the first team. [LNB]"The young lads won 7-2 in the FA Youth Cup [against Sheffield Wednesday on Wednesday] and they're a good bunch," said Henderson. [LNB]"There are some very good players there and hopefully there are some more players to come from the academy. [LNB]"The league and the Youth Cup is massive, and the teams that have won the Youth Cup have been very good sides. [LNB]"It's a good learning curve for younger players. I enjoyed playing in the Youth Cup and it's a good experience."
