Midfielder Park Ji-Sung has officially been unveiled as a Queens Park Rangers player at a news conference on Monday.

The South Korea international made over 200 appearances during seven years at Old Trafford after arriving from PSV Eindhoven. No fee has been revealed for the 31 year old, though it is thought to be in the region of £5 million.

Their plan is great, Park said to the assembled media, according to ESPN. I couldn't resist this plan and ambition. I know QPR want to improve and have ambitions to reach the next level and I will try my best to help. There were other offers but nothing compared to QPR.

It was a difficult decision [to leave Manchester United]. It is time for a new challenge and I think it's a great decision so that both me and the club can progress.

They want to be a bigger club and that ambition for me is a great challenge. They have great players and they are still hungry to get to the next level, to me that is very important.

Though Park was not always a regular in the first team at Manchester United his value has never been doubted, especially by manager Sir Alex Ferguson. The United boss consistently utilized the tireless industry and tactical discipline of Park in the biggest games both in the Premier League and in Europe. He claimed four Premier League titles and a Champions League winners' medal among his array of honors at United.

With Park now departed, there has also been speculation that Nani could soon be following him out of the exit door at Old Trafford. The Portuguese winger has two years remaining on his United contract and has yet to agree a new deal.

The Daily Star has reported that Manchester City are closely monitoring the situation with a view to swooping for the 25 year old.

This seems a far-fetched scenario as things stand. Just days ago, Nani revealed that contract negotiations were ongoing and he remains happy at Old Trafford.

We will see, Nani said when asked about his future, according to the Times of India.

I am very happy at Man United and have been there five years and won every title.

The manager has great faith in me and that's what is important. My agent is negotiating and we'll see what happens.

Even if Nani does end up leaving, the chances of Ferguson allowing the player to go to United's current bitterest of rivals are extremely remote. Ferguson one fought bitterly and ultimately successfully to prevent Gabriel Heinze from moving to Liverpool when he left United.
