Wilshere told reporters: "It was a bit of a strange one because I was going to training and remember reading that Tottenham Hotspur were interested. I thought it was a bit strange that we weren't interested.
"As soon as we got to the training ground he said to me that there was a chance it might happen. From then I was on to him every five or 10 minutes asking: 'is it done, is it done?'
"It was not done until 11.30pm and we were all buzzing because he's a great addition. With his pace and his work rate he can get up and down and cause the defence problems from inside or outside."
