Southampton boss Ruben Selles admits the Paul Onuachu deal hasn't worked out.
The striker has struggled since his January arrival from Genk.
I think sometimes it's difficult to come straight to the Premier League and it's hard to score goals especially in that position," said Selles.
There are some key positions where you need to be more exposed than the others and that's the number nine position. Probably the change in manager didn't benefit him, we went some places that we didn't go before. That's mainly it.
Usually when you get a player from the Belgian league or the French league, unless the team is very structured then they need time to adapt. And that's what happened. He probably has a different opinion but that's my opinion."
