In Mohamed Salah, Sadio Mane and Roberto Firmino, Liverpool have arguably the most dangerous attack in the Premier League. 

And manager Jurgen Klopp has done well to add to that forward line with the addition of Xherdan Shaqiri over the summer, a player capable of providing adequate cover for the trio.

That being said, to close the gap with Manchester City in terms of squad depth, Klopp could probably do with bringing in another forward, something which could happen in the new year.

The Breakdown

According to Marca (via Sport Witness), Liverpool are looking to add Athletic Bilbao's Iker Muniain to their squad for free next summer with the Spaniard's contract set to expire by then.

If there is genuine interest from Liverpool in Muniain, then supporters would likely want to see a deal completed in January rather than in June with the club currently competing with Manchester City for the Premier League title.

Nevertheless, regardless of timing, should Liverpool be able to acquire Muniain, the 25-year-old would be a very shrewd signing -- especially on a free transfer.

In La Liga, the Spain international has struggled for consistency at times and has stagnated somewhat considering what was expected of him after making such a huge impact under former manager Marcelo Bielsa.

However, Muniain still has a lot of ability and would be a great alternative to Mane on the left-hand side. The Athletic Bilbao youth product has raw goal-scoring potential that Klopp could unlock to devastating effect for his side.

At the cost of nothing in regards to a transfer fee, a deal for Muniain is one well worth pursuing for Klopp and Liverpool.
