Do you mean when he's joining the attack or when he's trying to help with the build up? In the first half, he was playing in front of Smalling, who had very few options when in possession (partly due to his ability on the ball, but also partly due to Arsenal closing down obvious passing lanes). During this period, I thought Fred looked hesitant to drop deep and provide a safe option. He seems more comfortable receiving the ball on the half-turn before playing a quick pass forward, rather than simply keeping things ticking over. Once Smalling and Lindelof switched places, Fred had a better time trying to influence the tempo of the game. Overall, I thought his direct style of passing allowed us to create some good chances despite having very little control over the game. And then when Dalot and Matic went off, we became very top heavy, and Fred had only Pogba to help him out in midfield. Naturally, the last 15 minutes or so did not go well, although the second goal was conceded by then.
