Both of which are the same thing.
And it is considered perfectly acceptable to start a sentence with 'And' for effect. Grammatically incorrect, perhaps, but rules are there to be broken. If you do it right.
I agree that there is nothing wrong with starting a sentence with the word "And", if, as you say, you do it right. The point I was making was that Naylor's sentence on its own does not make any sense. (see below)
"And the disappointment you expressed to fans in a message similar to this via your Twitter account on Wednesday night after handing in a transfer request".
In order to make a properly constructed sentence starting with the word "And" it should have been written:
"And we can also understand the disappointment you expressed to fans in a message similar to this via your Twitter account on Wednesday night after handing in a transfer request".
or even
"And the disappointment you expressed to fans in a message similar to this via your Twitter account on Wednesday night after handing in a transfer request is also understandable".
In these contexts it is perfectly acceptable to start the sentence with the word "and" and also the sentences have a meaning, unlike Naylor's sentence which makes no sense at all because it's unfinished. If he spoke those words to you, you would be waiting for him to finish the sentence to see what point he was trying to make. Naylor is a professional writer. He should be more aware of this than others.
