We are in such an awkward situation now, I think we have stagnated because it has just been the same team for too long. We have a lot of good individual players and the likes of Eriksen and Dele if they were to leave would definitely excel elsewhere. I think we do need to rejuvenate our squad a bit - players like Dier and even Dele have probably not progressed as far as we would have hoped, meaning we are in an awkward middle ground. I think Winks is a brilliant player but that is comparison to what we have, not the rest of the league. We are relying on him to be our best midfielder which I don't think is fair on him at this stage of his career.
To be honest I don't think anybody is blameless here, but I am certain in my opinion that simply changing the coach wouldn't fix it and it saddens me how quickly some people have turned their backs on the best Tottenham manager in my lifetime. I just hope he is given the opportunity to turn this round because if he was to go to Real Madrid I would not be surprised to see Kane, Lloris and Eriksen follow him there (he did bring a few Southampton players here remember). We don't want to be in a position where we have to replace an entire squad while being in the Europa like United, we need to keep hold of key players like Kane, Toby, Jan, Lloris, Son and Dele so we have a bit of a spine to work with when rebuilding.
