Who should Manchester United turn to?

So David Moyes didn't even make it a full season, but was allowed to spend huge sums on Juan Mata and Marouane Fellaini. More than anything, he seemed a little out of his depth - but it was going to be an impossible job to follow Fergie (unless another Class of '92 magically appeared).

But he's gone, and the only discussion now is who will replace him.

Ryan Giggs has the interim job, and has all his coaching badges. He wouldn't be a terrible choice, but I always feel that it's better not to coach players you have played with - at least in the last couple of seasons. They still have a relationship with you as a player, and you want them to ultimately to respect you as the boss.

Pep Guardiola is an option, but only if he wins everything with Bayern and feels he has nothing to prove there. There is talk that the establishment at the German club don't like his style of play, but I don't see him taking on a project like Manchester United.

The argument still stands that any manager will have to rebuild at Old Trafford. And here's why I don't think bringing in an older coach like Louis van Gaal makes sense.

United need to find a new identity, one that doesn't include Ferguson, Scholes, Giggs etc. The success they enjoyed over the last 20 years was based on the emergence of those youth team players - and let's be honest, it's highly unlikely to happen again in the next 25 years.

Hence, it's a longer term project. Chelsea and Manchester City are the big boys in England now - Liverpool may join them, but United and Arsenal face a battle to get back to the top.

Perhaps that was the thinking with Moyes - but he just didn't handle the transition well at all. Changing manager every season or two won't bring success, but they still need a manger and squad that will be able to compete at the top every year.

I doubt they could poach another Everton manager, but Roberto Martinez and Brendan Rodgers are the type of young, progressive coaches United should go for.

Barcelona need to evolve, not completely change

Barcelona take on Real Madrid in the Copa del Rey final today, and it's a coin toss over who wins the trophy. But win or lose, it's probably about time for some changes at the Catalan club. It's time for them to tweak their style, but perhaps with new players rather than a complete ideology overhaul.

The success of the Pep Guardiola era seems a long time ago. They are out of the Champions League, sit 4 points behind Atletico Madrid with 5 games left in La Liga and are still reeling from the Neymar tax scandel and 14 month transfer ban on players under 18.

But let's ignore the off the field issues and look at the team, and where they need to improve if they are going to challenge teams like Real Madrid and Bayern Munich for domestic and European honors.

Victor Valdes is done. It's a sad end to a great career with Barca, but there has always been a feeling that they could have improved in that area. Valdes is a very good 'keeper, but he's not in the top 5 in the world - he's barely in the top 5 Spanish goalies with Casillas, De Gea and Reina all arguably ahead of him. Who do they need? Maybe Thibaut Courtais from Atletico, but his parent club Chelsea are unlikely to let that happen. Or David De Gea from Manchester United - that could happen with United out of next year's Champions League.

Carlos Puyol is also retiring, and Javier Mascherano is just not a center-back.  Marc Bantra is decent, but not the man to help Gerard Pique lead that back 4 yet. Vincent Kompany is the man, but Manchester City won't sell him. Maybe Mats Hummels from Borussia Dortmund would make sense, but they probably need two defenders unless they can convert Sergio Busquets into a defender. Jordi Alba is quality, but Dani Alves is pushing on a little, so a full-back is needed too.

In midfield, Xavi, Iniesta, Fabregas and Busquets are all top players, but maybe a box-to-box type guy with a little more dynamism is needed - they probably don't regret selling Yaya Toure, but they'd love to have him back.

Barca need to cash in on players like Alex Song and Alexis Sanchez in order to strengthen in other areas. They produce a load of top quality youngsters, but players like Cristian Tello and Gerard Deulofeu need to establish themselves in the first team soon, or risk becoming bench players.

Tello has slipped down the pecking order after Neymar's arrival

I'm not going to mention Lionel Messi or Neymar. The team will be built around those two for the next 5 years - and they could beat most teams (especially in La Liga) on their own. But Barca do need to build again or risk falling behind. Maybe another striker like Roberto Soldado would give them another option up front - and Spurs would probably let him go after a miserable first season in England.

Barca need to change. The tika taka style is not dead, it just needs to evolve in order for them to compete for every trophy (which they expect to do) - maybe with a new coach, but definitely with 3-4 new additions.
