Alexis Sanchez was pictured celebrating with just half of his colleagues after putting Arsenal 2-1 up during their 3-2 win over Crystal Palace.
The 29 year-old is expected to leave the Emirates at the end of the season or even in January.
Sanchez’s commitment this season has been questioned by both pundits and supporters, but the Chilean has improved in recent weeks.
He put the Gunners 2-1 up in the second-half at Selhurst Park but was seen waving his arm towards teammates gathered closer to the half-time way, an indication that he wanted his colleagues to celebrate with him.
A confused Sanchez who had been joined by Granit Xhaka, Mesut Ozil and Shkodran Mustafi appeared to ask Alexandre Lacazette why the rest of the Arsenal side were celebrating elsewhere. Lacazette simply shrugged.
Sky Sports pundit Graeme Souness claimed the lack of unity in celebration can only be a result of squad division in the Arsenal team.
“I’ve only ever seen that if a team’s 5-1 up with five minutes to go, you would get that,” Souness said (via the Telegraph).
“Not when you’ve just gone 2-1 up and you’ve been under the cosh. That tells you it’s a divided dressing room, some of them are not having Sanchez and that (contract) situation.
“I think it’s clear, I think it tells you that there’s a dynamic going on in that dressing room that would suggest it’s not well.”
