New Barca coach will inherit Messi & flaws

When you get to manage Lionel Messi, it sounds downright silly to talk about the challenges awaiting Barcelona's coach-to-be. Yet whoever the Catalan club picks to replace Luis Enrique on Monday will not just be handed a star-studded team led by one of the best players in the world.

The chosen one will also inherit a handful of small, but serious flaws whose handling will determine whether he is a success or failure.

Media speculation has placed Ernesto Valverde, who recently left Athletic Bilbao, and current Everton coach Ronald Koeman as the leading candidates to replace a wornout Luis Enrique.

"On Monday, we will know officially and the coach that comes will have the qualities to carry this team forward," Andres Iniesta said after Barcelona salvaged its otherwise disappointing season by winning the Copa del Rey on Saturday.

"Now our task is to keep winning," Iniesta said.

Here is a look at the most pressing issues facing Barcelona's future boss: THAT MISSING BIT Despite winning a third straight Copa del Rey, Barcelona took a step back this season. But a look at its numbers will leave Enrique's successor the puzzle of figuring out why. Barcelona had the highest scoring attack in the Spanish league with the competition's top two scorers in Messi and Luis Suarez. It also defended well, conceding four fewer goals than champion Real Madrid.

In the Champions League it pulled off one of the most spectacular comebacks in the history of the competition when it roared back 6-1 against Paris Saint-Germain to overturn a 40 first-leg deficit.

Then it promptly slumped out 3-0 to Juventus after not scoring in either leg. Bridging that tiny gap between very good and sustained greatness is task No. 1 for Barcelona's incoming manager. MORE MASIA The steady stream of talent that once flowed from Barcelona's La Masia training academy into its first team dried up under Enrique.

The only homegrown player to earn a starting role under Enrique was Sergi Roberto, a midfielder converted to right back. Rafinha remains a reserve after returning from Celta Vigo, while Pedro Rodriguez and youngsters Munir El Haddadi and Sandro Ramirez left to find playing time. The academy that has produced current figures Messi, Iniesta, Gerard Pique and Sergio Busquets needs to reclaim its weight on the first team for the benefit of both. BARCA'S IDENTITY Nobody can say that Enrique wasn't a winner. He had a perfect first campaign in 2014-15, repeating the rare treble of Champions League, Spanish league and Copa del Rey first conquered by Pep Guardiola.

But many of Barcelona's purists complained that the team had lost its identity of dominating opponents through superior ball control by its midfield.

Since the arrival of Neymar and Suarez to join Messi up front, the focus on the team has shifted from its midfield to its attack.

If the Barcelona of old is to be the Barcelona of the future, its coach must get more from its other underperforming midfielders to help out Iniesta, who will turn 34 next season.
