According to the Daily Mail, Sakho has refused to travel to Austria with the rest of his West Ham teammates, as he looks to force through a move.
The French forward reportedly wants to leave the Hammers, but Parlour feels that he has gone about things in the wrong manner.
“You can’t do that,” the former Arsenal midfielder said. “How do your teammates feel? It’s not guaranteed he’ll leave. Is he going to help you out or put it in? It doesn’t help. The players have all the power, but I hope West Ham do well.”
Crystal Palace are believed to be leading the race for Sakho at this moment in time, according to the Daily Mirror.
Sunderland and West Bromwich Albion are also both interested in the forward, who has impressed during his first two season in the Premier League.
Sakho has hit 15 goals in 44 appearances in England’s top flight for the Hammers.
The 26-year-old did fall out of favour towards the back end of last season, though, and with competition set to increase at the Olympic Stadium next term - Sakho has reportedly decided that it is time to move on.
West Ham get their competitive season underway with a match against Chelsea at Stamford Bridge.
