Celtic have been linked with the Kilmarnock left-back Greg Taylor this summer.
According to Daily Record, the Scottish champions have now launched their move for the player and he is keen on a move to Parkhead.
It will be interesting to see if Celtic can get the deal over the line before the European transfer window shuts.
Taylor is valued at £3m by Kilmarnock and Celtic certainly have the means to pay that.
The Scottish giants sanctioned a big-money sale for Kieran Tierney earlier this summer. The fans will be hoping for more backing in the market for Lennon now.
