When asked about the possibility of more incomings, Cook said: “I think you will very rarely get a manager who says ‘that’s us finished.’
"I think when I look at the squad, does it need some help? Yes. Have we got some deficiencies? Yes. Can we solve those problems today? Let’s wait and see.”
The rebuild has included players from both the Football League and National League, with all but one of the new boys in their 20s.
And Cook says they have all settled in ‘terrificly well’ so far.
He explained: “When you bring in new lads the first quality they give you all the time is enthusiasm because they just want to get better. We have brought quite a few different players in now, the little friendship groups have developed in the squad now which is great to see, but the biggest factor of all is that they have got to be behind each other. During the season we will all have many highs and lows. I think the most important thing is that we show a real resilience about ourselves when the lows come and show how strong our character is to bounce back.”
"It will be a really tough fixture against good opposition,” Cook added.
"It will be a really tough game for us to come through unscathed.
"I think Boston will cause us a lot of problems on the night, probably different problems to what we had against Bradford and it is up to our lads to navigate those waters, hopefully come through it with a good away performance and a win. But, if not, we will look at the game and reassess and then look forward to the week’s training up to Dorking.”
