Paris Saint-Germain (PSG) fans are urging Lionel Messi not to pass the ball to teammate Kylian Mbappe in the Ligue 1 side's Champions League encounter with Maccabi Haifa.Messi lines up in Christophe Galtier's side's star-studded attack, alongside Mbappe and Neymar.The trio have been on fire so far this season, scoring 23 goals between them, but there have been murmurs of unrest between the three.Many believe Mbappe is selfish. The Frenchman appeared to walk away from a counter-attack in PSG's 5-2 win over Montpellier last month after not receiving a pass from a teammate. Mbappe and Neymar also argued over penalty duties in the same match.The forward has been in fine form, hitting nine goals in seven appearances.Lionel Messi has been a big part of that as he has flourished at the start of the new season. The Argentine has four goals and seven assists in nine appearances and has shown glimpses of his old self at Barcelona.However, fans are urging the Argentinian not to pass to his 'selfish' teammate.The duo are joined by Neymar in attack for PSG, with Vitinha and Marco Verratti in midfield. Nordi Mukiele is handed a start at right-back with Sergio Ramos, Marquinhos, Danilo Pereira and Nuno Mendes joining him in defense.Finally, Gianluigi Donnarumma continues in goal.Paris Saint-Germain@PSG_EnglishThe starting @mhfootballclub #𝗠𝗔𝗖𝗣𝗦𝗚67082The starting 1⃣1⃣ 🆚 @mhfootballclub #𝗠𝗔𝗖𝗣𝗦𝗚 https://t.co/VaHxBjXKLNAll eyes are on how Galtier's front three fare as they look to wreak havoc against the Israeli opposition.Here are some reactions from Twitter to Galtier's XI which has led to many calling for Lionel Messi to ignore Kylian Mbappe:SK10 𓃵@SK10_FootballMessi should play today for himself and for his fans, not to pour everything into selfish Mbappe and Neymar.705Messi should play today for himself and for his fans, not to pour everything into selfish Mbappe and Neymar.Ntolz (•_•)ᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠᅠ@Collen_Malete@PSG_English @mhfootballclub Another day, another chance, another match to watch Mbappe being selfish.4@PSG_English @mhfootballclub Another day, another chance, another match to watch Mbappe being selfish.Stav@stavfps@PSGhub LEOO LEO LEO LEO LEO LEO25@PSGhub LEOO LEO LEO LEO LEO LEOFPL Biza@Cvijovic1Milan@stavfps @PSGhub Hes getting a hat trick remember for later14@stavfps @PSGhub Hes getting a hat trick remember for laterNatural@Naturaleza_of@PSGhub 12 goals minimum1@PSGhub 12 goals minimumZabba 🇲🇽@Goatdiel@PSGhub Im so hyped for Messi to not shoot and pass to Mbappe for him to miss the chance11@PSGhub Im so hyped for Messi to not shoot and pass to Mbappe for him to miss the chanceRV ❁@RV_tango@SK10_Football It is time to bag that UCL assists record tho.2@SK10_Football It is time to bag that UCL assists record tho.PSG forward Neymar to outshine Lionel Messi and Kylian Mbappe against HaifaNeymar is shining alongside Lionel Messi and MbappeNeymar has started the season at his scintillating best amidst speculation of a rivalry with Kylian Mbappe.The Brazilian's future at the Parc des Princes had seemed uncertain in the summer with rumors of his departure swirling.However, PSG fans won't want the former Barcelona forward to go anywhere anytime soon. Neymar has ten goals and seven assists in nine appearances across competitions.Galtier has lauded the form of the Brazilian, saying (via Yahoo!):"Neymar has had a realisation in relation to last season when he didn't perform as well, when he was less involved.He continued,"It would be facile to suggest that his good start to the season is only down to me and my staff. He arrived back on time, in great shape, and had worked well beforehand. He's an artist, and when he's on form, you can see that."Tonight may be another night for fans to cast their eyes on the Brazilian, who is playing some of the best football of his career.He is up against a Maccabi Haifa side that lost 2-0 to Benfica last time out. The Israeli side's centre-backs Dylan Batubinsika and Sean Goldberg have a huge job on their hands.
