December PL POTM Investment: Alisson
Reasoning: Not only is Alisson one of the cheapest 85 rated players, he also has a good nation, good league, and, most importantly, good club.
With 6 goals and 4 assists in a 7-0-0 month December, Salah is all but certain to win Player of the Month. There is a good chance that Liverpool players will be required for the SBCs. Alisson should rise in the hype regardless of whether he is needed or not.
Target BUY: Less than 9k
Target SELL: When you are happy with the profit and/or see a better investing opportunity.
