I think Davis rolling the balling to Fonte every time will only be seen against the weaker teams. Tranmere only had one striker and they weren't able to press the Saints back line when Davis had the ball, hence why he was able to give it to the defenders. Huddersfield will play two upfront and wide midfielders pressed on, thus they may force Davis into more long balls.
It is still very good to see and I hope it continues as it means Saints keep the ball and build the attack looking for an opening.
