Lionel Messi is on his way out of Barcelona. 

After 16 incredible seasons at Camp Nou, the Argentine is done. 

He's fallen out of love with the club's project and wants to move on for a new challenge. 

The news sent shockwaves through the football world. Many supporters expected Messi to stay at Barca forever as a one-club man. 

But it seems that won't be the case. Manchester City are favourites to sign the South American superstar, while Juventus and Paris Saint-Germain are said to be in the running. 

If Messi really does leave, Barcelona will have to replace him - and quickly. After all, they face losing a player who has scored 638 goals and provided 195 assists in 850 games for the club.

Those, are quite unreal stats. So who would be fit to lace the forward's boots and replace him once he's gone? 

Messi would leave a huge hole to fill at Barcelona

Well, according to the latest betting odds, 10 big names have emerged as favourites to move to Camp Nou. Check them out:

  • Neymar - 7/4 odds
  • Sadio Mane - 7/4 odds
  • Jadon Sancho - 5/2 odds
  • Kylian Mbappe - 3/1 odds
  • Lautaro Martinez 7/2 odds
  • Pierre-Emerick Aubameyang - 4/1 odds
  • Raheem Sterling - 5/1
  • Memphis Depay - 11/2
  • Harry Kane - 6/1
  • Paulo Dybala - 6/1

That's a list full of superstars, isn't it? 

Aubameyang and Kane are amongst favourites to replace Messi

GIVEMESPORT's Ollie Browning says:

It looks like Barcelona really will have to prepare for life after Lionel Messi. A good first step would be to bring in a world-class replacement - and quickly.

Some of the names on the list above are more likely to move than others. Martinez has long been linked with a move to Camp Nou, for example.

As has Neymar, who could return after three seasons at PSG... but will he really want to play without Messi by his side? 

Would Neymar want to return without Messi?

Other names on the list look less likely to move. 

Mbappe, Sancho, Sterling and Dybala would all demand huge transfer fees and it's unlikely Barca would have the money to finance such moves, especially if Messi leaves on a free transfer. 

Sancho and Sterling are linked with Barca

This, of course, all hinges on the Argentine actually leaving. But if he does walk, replacing him with quality will be quite a headache for the Blaugrana.
