As impressive as Trent is as a talent, Stevie G was supernatural. He could play most positions on the pitch and be in the top 3 or 5 in the PL - midfield, number 10, striker 🙂, right winger, right back, etc. I can't prove it obviously but I am confident if he dons the gloves for half a season, he will put in some all-time great performances as a goalkeeper. His ability to instinctively understand the needs of the position and adapt was unparalleled. Of course, his physical and technical ability helped but I am yet to see great technical players as adaptable as him. So we should be careful with the if Gerrard can do it, why not X?
That said, I am not saying it is not worth trying out TAA at midfield. My concern is that there is a difference between a player who starts at RB and drifts to midfield and a midfield player. In attack, TAA has space in front of him, he can attempt deep lying crosses. His view of the game is along the sidelines and across, more of a 90-degree left quadrant view. Because of the space in front of him, he is able to build up speed with the ball, build momentum and then take on players.
All of that space will not be available if he plays in midfield. It is a more congested area. He becomes easier to press. It might not be viable for him to build up speed and power past players. To make crosses, he will have to drift to the right-hand side. He will need to have a 180-270 degree field of view while playing.
Folks are concerned about TAA's ability to track running or drifting behind him as an RB. Won't that issue of inability to track runners be magnified if he plays in midfield, particularly a Klopp midfied which demands a lot from a defensive point of view?
