The subject of Manchester United's midfield last season has filled many sports columns, with views ranging from how ineffective it was to who they need to bring in as much-needed replacements for particular under-performing players.
Michael Carrick had an uncharacteristically inconsistent season. He may not be the flashiest of players, but he could always be relied upon to be relatively solid with a good range of passing.
Last season, however, he looked as if he was lost and had no support in that midfield, mainly because Tom Cleverley was probably aimlessly running around somewhere near the corner flag.
Darren Fletcher seems a shadow of his former self since his recovery from illness, Shinji Kagawa has yet to be given a fair chance at actually playing in the position he considers his best and is unlikely to given the arrival of Juan Mata.
United clearly need major investment in this particular area and have been linked with some of the world's best midfielders.
One of those players is the Juventus midfielder Arturo Vidal, with the Chilean being linked with several of football's big guns. The former Bayer Leverkusen man has become an integral member of the Turin giants and has helped them to consecutive Serie A titles.
This signing would make a lot of sense for United as he would bring several different qualities that they are currently lacking in the centre of the park. Vidal is classed as a true 'box-to-box' midfielder, with high energy levels complimenting his intense style of play.
Nicknamed "The Warrior" in Italy because of his tough-tackling, Vidal is a 'complete' midfield player. He can support in both defence and attack, break up play and create chances, chip in with goals and add a level of steel to a midfield that so many world class teams need.
All of these qualities have been lacking at Old Trafford and every year since his retirement, the press talk about United replacing Roy Keane. There is no replacement for Keane, football has evolved even since his time at the top, but there is still a need for a leader who can grab a game by the scruff of the neck.
This level of quality comes at a price though, with a staggering €60 million price tag being quoted for Vidal. However, at 27-years-old he is about to hit his peak and if he transforms United's midfield, then it would be a solid piece of business.
Louis van Gaal is acknowledged as being a big fan of Vidal - apparently always wanting to sign him when he was manager at Bayern Munich before he went to Juventus - and will be watching him with interest at the World Cup.
He will face competition, however, with Real Madrid being linked after former striker and Chilean hero Ivan Zamorano admitted to recommending his compatriot to Madrid.
The United squad needs some rebuilding work to be done and to bring in one of the best players in the world will certainly be a great start.
