Eriksen was a great signing and has improved us massively. He's been such a massive part of our success this season, in allowing us to hold onto the ball and transition. And he was free, which meant we could get lisandro, casemiro and antony, all of whom sped up our rebuild and made it so that next year we can aim at just 2/3 positions and depth, which we did not expect last may.
But he can't compete with teams like city over 90 minutes, as was shown today. They dominated after half time cos he wasn't keeping up (i also think we couldn't hold onto the ball after Martial went off).
For next summer I guess a younger, fitter player who can play his role is a second priority after a striker.
If Garnacho continues as he's been doing, Sancho comes back, and Pellistri turns into an option on the right, then we're suddenly in good shape with just those 2 signings. We'd have great squad depth for the first time in ages.
