He was a big miss due to Elmo being a catastrophe. But guilbert was a top 5 rb last season when playing. And only behind Hakimi, Cancelo, Trippier and Kimmich (does he even count plays as a CDM). And Guilbert had a sending off in that period. Which is pretty rare for his career one every 50 games.
And whilst that may have been a hot run of form for him. The fact is he was one of the best players in Europe last season which you couldn't really say about cash at any point.
