Kemar Roofe's best position in Leeds system could not have been made more evident against Cardiff

Kemar Roofe played as both a central striker and an attacking midfielder during Leeds United's defeat to Cardiff City on Tuesday.

Since Kemar Roofe arrived at Leeds last summer, there has been plenty of debate surrounding what his strongest position actually is given his ability to play as a striker, winger or number 10.

But surely, Tuesday's defeat to Cardiff could not have done more to highlight that if Thomas Christiansen is to continue adopting a 4-2-3-1 system, Roofe has one role in the side that suits him best.

The former Oxford United man began the game as the sole striker with Pierre-Michel Lasogga on the bench, but struggled to get a sniff of the action during the opening stages of the game.

The problem appeared to be that Leeds looked to use the wings to get into Cardiff's final third, and when the likes of Gjanni Alioski, Pablo Hernandez and Stuart Dallas were in a perfect position to cross the ball into the box, they would look up to find Roofe isolated amongst a Cardiff defence that would have been favourites to win every header that was up for grabs.

By the end of the half, Roofe appeared to be dropping deeper than the three playing behind the striker to get onto the ball.

It was during the second-half when the £3 million signing (via BBC Sport) looked to be at his most threatening, but that was only when Jay-Roy Grot replaced him as the sole striker and Roofe dropped into a central attacking midfield role.

Of course, Roofe would get the goal in that position, and generally looked a lot more threatening when able to collect the ball from slightly deeper with the ability to run at the defence.

It would be wrong to suggest that the 24-year-old cannot play up front - he scored a header against Nottingham Forest earlier in the season when leading the line in the wake of Chris Wood's departure - and if Christiansen changes to a different system, Roofe up front could be a game-changing option, but in the Championship, he seems so much more threatening in that number 10 position, dropping into space and using his skill while running with the ball, and that is arguably how Christiansen should use him.
