The 25-year-old attacking midfielder has been in impressive form for Eintracht Frankfurt this season, scoring nine times in all competitions and catching the eye.
Kamada is being closely monitored by several clubs across Europe ahead of the next summer transfer window.
Leeds are interested in him but they are only likely to move for him if they can secure their Premier League status this season.
However, even if they do move for the player they are tipped to face competition as, according to Italian outlet Calciomercato.com, Kamada is also being watched by Spanish outfit Sevilla ahead of the summer.
The Japan international’s performances have been closely monitored by the Spanish giants with a view to potentially signing him.
The 25-year-old has also played a key role in Eintracht Frankfurt’s run in the Europa League and scored in the first leg of their semi-final against West Ham.
He will have a year left on his contract with the German club in the summer and for the moment there is no agreement over a new deal.
