Pedro Obiang left West Ham for Sassuolo in the summer of 2019 for around £7.2 million, according to BBC Sport.
The midfielder moved to the Hammers in the summer of 2015 from Sampdoria, and he went on to make 116 appearances for the club (Soccerbase).
The 27-year-old was a popular figure in east London, and many West Ham fans were sad to see him leave. They were even more angry when the Equatorial Guinea international was not replaced.
The Hammers could really have done with someone like Obiang this season.
So how has the 27-year-old got on since joining Sassuolo?
Obiang has played 20 Serie A games this season, racking up one goal and one assist in the process (Transfermarkt).
Now, he is a defensive midfielder, so we can’t read too much into his lack of attacking output.
His defensive stats make for slightly better reading.
In those 20 league games for Sassuolo, the 27-year-old has a very impressive pass completion rate of 88.5%. That percentage comes from an average of 47.4 passes per game. He also averages 0.8 key passes per game (Who Scored).
Obiang has averaged 2.2 tackles, 1.1 interceptions, 1.5 clearances and 0.5 blocks per game in those outings as well (Who Scored).
Sassuolo are enjoying a decent campaign, and are currently sitting in 12th spot in the Serie A table, just five points adrift of sixth place. And Obiang is obviously a key part of Roberto De Zerbi’s plans, having played in all but three of his side’s league games this term.
Considering how porous West Ham have been at the back this season, perhaps selling the 27-year-old was a mistake.
He would surely have made a big difference for them in what has been an extremely challenging campaign thus far.
