West Bromwich Albion boss Alan Irvine conceded Saido Berahino struggled to make an impact in defeat to Newcastle United.
The striker now joins up with the England squad for the first time.
"He probably had his poorest game but people have poor games," he said.
"Everybody, including myself, will probably go away asking 'Is it because of what has just happened to him during the week?'
"But of course you can have a poor game any time.
"I would like to think what happened during the week has given him a massive boost and maybe it didn't happen for him today for whatever reason.
"Give Newcastle credit, we probably didn't play as well as we needed to do."
