"Chelsea Harbour is all set for the Leinster National and he's in great nick at the moment," said Mullins.

"He's got a slight pull at the weights over Preists Leap compared to the Thyestes and I would be hopeful that we would be able to turn the tables."I didn't think he ran up to his form in the Irish Hennessy and I was a bit disappointed with the run because he just dropped out on the back straight."He's been running in soft and heavy conditions all season and, although he loves that sort of ground, he can also run a decent race on quicker going.

"He's been given 11st in the Grand National which means he is rated 8lb higher in Britain than in Ireland and I think he was hit hardest of all the Irish horses. Chelsea Harbour continue his Grand National preparations in Sunday's Lucan Racing Leinster National at Naas.

Chelsea will be desperate to regain the Premier League crown after finishing second to Manchester United in the last two seasons. Former manager Jose Mourinho, bankrolled by owner Roman Abromovich's millions, brought the first title to Stamford Bridge for 50 years when the Blues lifted the trophy in 2005. Chelsea became only the second team to win back-to-back Premier League titles when they clinched it a year later. Mourinho left the club by mutual consent in September 2007.

Shortly after, he led the team to the UEFA Super Cup after a 1-0 win over Real Madrid. The FA Cup followed in 2000. Vialli was replaced by Claudio Ranieri in 2000 and he led Chelsea to another FA Cup final appearance in 2002. 

Russian billionaire Roman Abramovich bought the Blues for £140 million. After a trophyless season, he appointed Mourinho as new Chelsea manager and there was instant success. In 2005, Chelsea won the Barclays Premiership and League Cup, along with a Champions League semi-final appearance.
