Think Mctominay was massively underrated on here. Think he s the type of player Fergie would have in the squad till retirement imo.
6 ft 5, covers as much ground as anyone we've had, quite good In both boxes ( we could really find a use for him on set pieces, remember him always guarding the most dangerous ball header, leaving Maguire to cover the 6 yard box ). He's an athletic freak and you will not find players of his size covering anywhere near the ground he does and his stamina was that of a much smaller player. His biggest issue was always technical skill, and the inability to operate in very tight spaces (hardly surprising with players of that size, where the likes of Pogba and Busquets are exceptions). Mourinho and Solskjaer players him deeper to find space, while Ten Haag used him as a dummy in midfield to bypass the press and drag defenders with runs.
Defensively, under Ten Haag, he was a lot less involved than under Soskjaer, and mostly provided a screening block in front of the defense rather than outright chasing the ball/tackling players. Think it's because he s quite clumsy when facing the small agile type ( think Hazard, Silva ...) and would foul quite easily. This was okay under Soslkjaer (with a box defense of Maguire, Lindelof, Bissaka, Shaw, Mctominay), but a lot more risky under Ten Haag ( Martinez for Maguire, maybe Malacia/Dalot for Shaw ). So just by covering the center, even without engaging, would leave our combative, smaller, more agile defenders ( Dalot, Martinez ) to handle the attackers in more crowded areas. This is much more risky with Mainoo/Eriksen for Fred, who was a better ball winner than both combined.
The amount of criticism McTominay used to get for "hiding from the ball" under Ten Haag, whilst his instructions were obviously to go to the most crowded areas, dragging defenders away from the more skilled Bruno, Rashford, Garnacho etc. was always surprising. Not just on here, I remember in a game ( either Newcastle or Aston Villa) Dalot got on the ball in space and Mctominay absolutely sprinting to the center, dragging with him the 2 midfielders and then staying between them and was made fun of for 5 minutes straight by the ESPN crew, ignoring that Dalot managed to find Bruno in the space that should have been covered by one of the players Mctominay was hiding in between.
Anyway, while he shouldn't have been 1st choice, he's very useful tactically in a Wan Bissaka sort of way, just applicable to more matches, more often. Wan bissaka is extremely useful in completely shutting down the right side (lock down defense) and can nullify some teams biggest threat, whilst Mctominay can have an impact in a lot more games when used correctly. Think we d have seen a lot better from him as an impact player if our team, at any point, were not rubbish at keeping the ball, meaning adding him to the team made our barely functioning on the ball abilities disappear.
A bit similar to adding Ronaldo to one of the laziest teams in Europe pushed us over the edge.
Anyway think Fred was the better player overall, just not as useful tactically. It's easier to find a generally capable hard working midfielder than a physically gifted battering ram. We have a big enough squad to have role players with a job even when the squad is full more so than just cover to rest starters.
