Kane and Bale is enough when we have Bergwin, Lucas and Lamela and Ali backing them up. If anything we need a replacement for Eriksen more than a back up as we still lack that creative spark. Lo Celso is simply not a replacement for Eriksen
He's not a direct replacement but we're hoping NDombele can help fill that void alongside Lo Celso right? He's performances are pointing in the right direction. If GLC and NDombele can click, they can be the force in midfield we were looking for.

I tend to agree with you but how much is it going to cost us to bring on a back up striker? I doubt it transforms our play in any way shape or form but I think what it will do is somewhat reduce the burden/stress on our players. Kane/Bale are both injury prone and if one of them goes down alongside Son, we will be definitely short of options. Again, if it doesn't cost us an arm and a leg, at this point with Son down, it's worth it just to bring one in as an insurance policy.
