How do you know we'll only have 4 strikers?Your assumptions might not be entirely correct. How do you know that Shuey didn’t want a pacey player as his main priority and that Georgie Kelly was 2nd or 3rd choice option perhaps? Maybe Shuey didn’t try that hard to sign Kelly hence him going to Rotherham instead.
Difference last time is we already had 4 strikers on the books which included Garrick who’s not the slower physical type. Kelly would have been the 5th striker so it made a little more sense to have a different type of striker. This time we’ll only have 4 strikers.
You are making up a narrative to try and fit your own erroneous view. It's nonsense saying he didn't try that hard.
