When Mal came back midway through the 1978/9 season, Book's team was showing signs of decline. We weren't in a relegation fight, but we were two thirds of the way down the table, out of the League Cup and had lost as many home games by Christmas as in the previous two and a half seasons put together, IIRC. We'd had a two or three great nights in the UEFA Cup that autumn, especially the tie against Milan, but displays like that were the exception and the team did look in need of a bit of a shake up.
Book's two big signings as he looked to build on the excellent season in 1976/7 had both disappointed - Mick Channon got a goal every 3 games for us so hadn't proved a disaster but he wasn't worth the big fee we paid for him, while Paul Futcher looked out of his depth even though we paid big money for him by the standards of the time and Kazi Deyna was finding the English game hard to adapt to. Colin Bell had come back but was manifestly not the same player and we badly needed another top-class midfielder rather than stop-gaps along the lines of Conway and Viljoen. (Dennis Tueart said in his autobiography that we should have gone for Graeme Souness in 1977 rather than buying Channon, which I think is an excellent call, actually).
However, while I do think that some surgery was needed, I mean a couple of buys and maybe giving the odd kid or two a game, not ripping the team apart as Allison did. We let a lot of players go who could have continued to play an important part at City into the 1980s - not just young players like Barnes and Owen (whose departures gave the lie to the idea that Mal's main aim was to rejuvenate the side) but the likes of Watson and Hartford.
It does need to be pointed out, though, that the reason the episode was so catastrophic was that we made a vast loss on the transfer dealings. If we'd replaced one set of players with another inferior group but made a profit or broken even, that would have been one thing. However, we spent a fortune on the new players, sold the old ones cheap and thus saddled ourselves with a huge debt that hamstrung the club for years. Daley and Robinson cost more than GBP 2.15 for the pair, while Barnes, Owen, Hartford, Watson and Brian Kidd were sold for just under GBP 2 million combined. It's enough to make you weep.
Swales and Allison each blamed one another for this. Tony Book, though, in his autobiography backs Allison up and claims that it was Peter Swales who negotiated the fees for Daley and Robinson - and I'm inclined to believe Book, who I think is a very honest guy. Allison deserves roundly castigating for what happened at City in his second spell, but we have to remember that Swales was just as culpable, if not more so, for the way it had a catastrophic impact on our club for years to come.
