Day 12 of your Millwall Christmas Calendar sees us looking at the much loved Mahlon Romeo.

The young full back has already proved his worth to the Lions fans during their promotion winning season and the eight placed finish last time out.

His pace and trickery epitomises what is expected of the modern full back and more times than not, he is always offering width to Millwall’s attacks when Jed Wallace drifts inside.

However, Romeo’s eagerness to get forward has left Millwall defensively vulnerable as naivety to dive in to tackles has meant opposition target the Lions right-sided weakness of their protective amour.

In the defeat against Birmingham, Romeo thrived. He dribbled his way into dangerous positions and linked up well with Wallace down the right hand side.

In the game against Brentford, Romeo had a nightmare. Countless times he was dragged out of position and gave away needless fouls that led him to be rightly dropped to the bench next time out against Norwich.

Having said that, the Antiguan international is Millwall’s preferred right back. He is an exciting player to watch and has the potential to play at the very top. However, Romeo will need to be improve in both boxes in the second half of the season, because if he is going to bomb forward he will need to make it count.
