Players are always going to get knocks so injuries are inevitable, but its frustrating to see how many muscle injuries (aka the "pulled groin" or "hamstring") we've suffered so far this season. Surely these injuries are fatigue related and are bound to happen with such a thin squad, particularly during the busier fixture periods.
For example, Gerrard suffered his 'hammy' 60 minutes into West Ham, following 90 minutes against Hull, 90 minutes vs Norwich... all in the space of 7 days.
Flanagan wasn't used to playing 2 games per week, so the busy Christmas period burned him out, similarly for Sakho (Man City and Chelsea games in particular).
In effect a larger squad does two things: firstly, it allows adequate cover for when players do pick injuries; and secondly, avoids injuries in the first place due to fatigue.
Assuming we can get players back from injuries and avoid having as many as we've had until now the rest of the way we might be able to survive this season without major additions. However, if we make Europe next season we'll need at least 4-5 additions over the summer (one attacker/winger, 2 midfielders, 1 defender/fullback, and a better backup goalie)
