ENZO MARESCA will be anxiously checking his phone on Wednesday morning as his South American stars compete in their countries’ final World Cup qualifiers.
Brazil internationals , , and Andrey Santos will travel back to London from Bolivia after a match at the highest international stadium on the planet.


La Paz’s Estadio Municipal de El Alto sits at an energy-sapping altitude of 4,150m — or 13,615 feet — above sea level where tourists often need days to adapt to the lack of oxygen.
Playing there was banned by in 2007 — until a campaign backed by saw that decision reversed.
described his experience as “inhuman” after a World Cup qualifier in 2007 at a different stadium in the city — 560m lower than El Alto — where in the changing room after struggling to a 0-0 draw.
So Maresca can expect Pedro, Estevao and Santos to return to the club’s Cobham base later this week out of breath and exhausted following a 14-hour flight.
Midfield dynamo will also be returning from on a long flight ahead of the Blues’ Prem derby clash at on Saturday evening.
Those marathon journeys will give Maresca a massive selection headache ahead of the potential banana skin fixture.
All eyes will be on Thursday’s training session to see who makes it and who will return to action on Friday before Saturday’s 8pm game.
Either Pedro, Caicedo or Estevao have been involved in every one of Chelsea’s seven goals this season — showing how heavily they have lent on their South American stars.
The Blues have seven players from the continent in their first-team squad — the highest number from any club in the league.
Maresca, though, can at least rely on his three Argentine players.
‘s new boys and Alejandro Garnacho were not selected by Lionel Scaloni, while Enzo Fernandez enjoyed a Greek getaway with his family, absent from his national team due to suspension.
After injuries to Palmer, , and , the Blues’ medical room has become even busier – as Dario Essugo picked up a knock while away with .
The 20-year-old, who signed from Sporting for £18.5million this summer, sustained a thigh injury on international duty and is now expected to miss the next up to three weeks.
Essugo was bought in primarily as cover for the seemingly indestructible Caicedo, but the Ecuadorian midfielder has also been struggling this season according to .


So much so, that Caicedo was missing from Ecuador’s 0-0 draw against Paraguay due to ‘physical discomfort’ – though he is expected to feature against on Tuesday night.
That leaves Chelsea, who have a midfield worth more than £300 M, facing a problem with also out and not ready to return.
If Caicedo is forced to miss any upcoming games for Chelsea, they may have a midfield depth of Santos, Fernandez and .
Maresca’s side, however, will be hoping to be boosted by the return of , who teased he will be ‘back soon’ in his latest Instagram post.
It remains unclear exactly how soon that might be but the Chelsea boss will be hoping, if he does miss the game against Brentford, he will be back in time for a huge tie away at four days later.
