West Brom boss Tony Pulis admits his players are struggling with their self belief.
Pulis is eager to rebuild confidence over the next two weeks, but will have to do it without many of his first-team players who are away on international duty.
“The concern is obviously the confidence with the players and everything else," said Pulis. “The biggest worry is the players. I've been a manager for a long, long time. Confidence is the major factor with the team and with the players. If I see a drop off with the players then that would be a concern."
Pulis expects such a poor run to impact the mentality of his players, but refused to criticise the effort that his team put in.
“They've worked really hard again," he said. “I don't think anybody can say that people were hanging around or standing about, they've had a right go."
Burke is working his way back from injury.
"The thing that Oli gives us is an attacking presence, which is probably something we've lacked in our games so far this season," said under-23s boss James Shan.
“In the games that he's played for us he has shown a directness and a willingness. He's got the ability to go past people so hopefully he'll get us up the pitch."
