Southampton boss Ronald Koeman wants Senegalese striker Sadio Mane to replicate the form that brought him a hat-trick on Sunday.
Mane, 24, led his side to a 4-2 win over Manchester City, bring his total league goals for the season to 10.
Koeman said: "Sadio is a little bit unpredictable sometimes.
"He's still a young player, and young players they need sometimes to be more consistent. Sadio was focused and clinical (on Sunday)."
Mane has had a mixed season for the Premier League side.
He suffered a barren spell between November and March when he failed to score in 19 league appearances.
But he has rediscovered his touch in front of goal during the season run-in, finding the net seven times in his last six league matches.
