Why defend the indefensible? Suarez is the main culprit!
Given the inordinate amount of scoring opportunities (usually more than half) Suarez strike rate is poor. Let's analyse Liverpool 's plight and the pathetic performances of the offence.
Why isn't he clinical?

Perhaps we should look at Messi's to contrast.
Messi creates or strives to score everytime he gets an opportunity. He does not look for cheap fouls or go down easily. That's what make this natural leftie the best footballer currently playing.

Liverpool had more scoring opportunities (17 shots with 8 on target) & better goal opportunities than Arsenal (11 shots with 7 on target).
And Suarez HOGGED more than half of them, some of them clear cut opportunities. Even the free kicks
But more than 50% of that he tries to comp a foul or penalty. His on field body language reveals it.
PL referees are wise up to him & so does Liverpool's opponents.

Suarez is not an HONEST footballer. He is a SERIAL Cheat. That's a fact
This is a general consensus amongst my teammates (most of them red fans and one of them is a scouser) when we were discussing Liverpool's plight and pathetic performances over our customary post match (Fridays) drinks. I pinpointed that Suarez is a liability and they agreed with me.

Yes Messi does cheat too (Hand of God) but with his natural left hand.

Cogitate, Correlate & Communicate. Go figure.
