"Unfortunately Alan was away on holiday and when he came back he went straight off on tour with Manchester United, so we haven't had the opportunity to speak to Alan.
"But I'm sure that he is well aware of our interest and I'm sure that in the next few days the opportunity to speak to Alan will present itself.
"And if it's right for Alan and if it's right for Middlesbrough, then I'm sure that it's something that we might well conclude, you never know."
Boro boss Gareth Southgate is also keeping his fingers crossed that Smith will agree to enter the next chapter of his career at the Riverside.
He added: "It's a situation that we are monitoring very closely.
"It's apparent that his future at Manchester United isn't certain and he falls into the category of being a quality player and a good character.
"That is of course someone that would interest us.
"I think the situation is that he understandably wants to stay and fight for a place at Manchester United.
"Nothing else entered his mind over the last couple of weeks.
"Now it would appear that that situation is changing by the day, so if he wants to move on obviously the mindset changes."
