There are bound to be changes in the Liverpool squad as Brendan Rodgers continues to revamp his side.
One player the Reds manager shouldn't let go, besides the obvious in Luis Suarez, Lucas Leiva and a few others, is Pepe Reina.
The Spanish goalkeeper has been linked (via the Metro) with a move to his former club, Barcelona.
A return to Barcelona would certainly be attractive to Reina, given the Spanish side's current situation with Victor Valdes.
In turn, Goal.com reported in December that the Reds were interested in Birmingham City Jack Butland.
If both deals were to occur, Liverpool would gain the services of a player who is believed to have a bright future in the game.
They would lose the experience of Reina but gain the long-term potential of a possible future No. 1 goalkeeper for England.
Here are five reasons Liverpool should resist selling Pepe Reina.
