By this time last year we'd brought in Sels, Gayle, Ritchie, Gamez and were a day away from signing Hayden. 3 signings followed in late July/early August, with another 3 in late August.
Definitely seems a lot slower this summer, especially given that the need for signings is arguably far greater as we need players for the first team as was so abundantly clear last season, whereas at least half of the signings last time were about fleshing out the squad and having competition for places all through the team.
