According to German newspaper Hamburger Morgenpost, Celtic scouts have been watching St. Pauli forward Lennart Thy ahead of the January transfer window.
The Bhoys strengthened heavily over the summer with Logan Bailly, Saidy Janko, Jozo Simunovic, Dedryck Boyata, Tyler Blackett, Scott Allan and Nadir Ciftci all arriving at Celtic Park.
However, manager Ronny Deila is still on the lookout for more reinforcements, and having taken Carlton Cole on trial last week, it's clear that the Norwegian wants to land another attacking threat in the near future.
Now, German newspaper Hamburger Morgenpost report that Celtic scouts have been watching St. Pauli recently, notably for forward Lennart Thy.
The 24-year-old, who can play at full back, on the wing or up front, Thy has pace and versatility, which could come in very handy for manager Deila.
A big boost for Celtic comes in the form of Thy's contract situation. The former Werder Bremen man is out of contract at the end of the season, meaning Celtic could land themselves a bargain.
They could either target Thy in a cut-price deal in January, offer him a pre-contract agreement so he can move to Glasgow for free next summer, or simply wait to see if St. Pauli offer him a new deal before making a move at the end of the season.
Thy may not be the big name that Celtic fans to see, but he offers versatility all the way down the right hand side, and could be a cost-effective option for the Bhoys.
