Russell Martin revealed he challenged Michael Obafemi to make a decisive impact before summoning the striker from the bench in Swansea City's 3-2 win over West Brom.
The Republic of Ireland international came on shortly after the hour mark at The Hawthorns Stadium and struck his second goal of the season two minutes from time to earn Swansea all three points against Steve Bruce's side.
And Martin believes the forward's telling impact against West Brom will prove to be the perfect tonic following a turbulent period.
