Okay found the stats I was looking for from Squawka... interesting comparisons between 2012/2013 and 2013/2014:
Average claims last season vs this season:
- Not only did Mignolet come out to claim the ball less in 2013/2014, he also failed more often to win the challenges.
- Mignolet was miles better than Reina in 2012/2013.
- Decline for Begovic as well in this department, but de Gea had an improved season in this area, going error-free in 2013/2014.
Ball distribution accuracy last season vs this season:
- Marked increase in goal kicks from ground (I assume, since there's a "from hands" column) for Mignolet from 2012/2013 to 2013/2014; however that could also be attributed to the shortening of the distribution distance (from an average of 60m to 25m)
- Reina was definitely king in this area (goal kicks) in the league last season, although he also didn't distribute the ball a lot further (32m)
In summary, it could be suggested that, statistically,
- Mignolet progressed in distributing the ball in his first season at Liverpool versus his last season at Sunderland
- Mignolet declined in coming to claim crosses and coming to claim them successfully, over the same time frame
