The Buddies manager is recharging his batteries on a family break, but rarely has his phone been out of his hand.
Yet while he is keen to do a bit of wheeling and dealing for Saints, there is some trepidation every time the phone goes.
Kenny McLean, who has remained in Paisley this week as his team-mates jet off for some respite to work on his rehab after having surgery on his knee, has been linked with moves south of the border.
Wolves in particular are rumoured to be keen on the 21-year-old, and Lennon will be relieved if his incoming calls are kept to a minimum.
"If this window closes and Kenny is still a St Mirren player then I will be delighted," said Lennon.
"I have taken a few calls from agents, but as of this moment there have been no bids for him – and that's the way we would like it to stay.
"He is a key player for us and we would like to keep him.
"But we are also realistic and if an offer does come in then we'll have to take it from there.
"The good thing is that financially we are not in a position where we would need to take the first offer that we got for any of our players.
"We can pick the best offer and we can hold out for a decent deal. You also want it to be a good move for the player as well.
"There has been a fair bit of speculation about one or two of ours, but as of yet there are no bids that have come in."
Lennon's attempts to bolster his own squad with MLS forward Dom Dwyer fell through, but he remains hopeful of perhaps adding a striker to the ranks.
Youngster Thomas Reilly suffered a broken ankle last month and is out for at least another eight weeks, and Lennon believes his side are a little light up front.
"It is an area that we would like to strengthen, but crucially, we have to bring in players who we believe can enhance the squad," he said.
"And it also depends on what happens with our own squad. If we end up a few bodies down then we would really need to think of replacing them."
Lennon will jet back into Glasgow tomorrow and he is confident that the break will have done the squad the world of good.
He said: "This is us going into the business end of the season and it does get draining.
"To be able to go away and properly switch off from it all for a week definitely brings a benefit.
"I have been in touch constantly with what has been going on at the club back home but even just being away from the day- to-day duties give you a bit of a boost.
"We'll be back looking forward to the Ross County game and hopefully we can build on the form that we have shown over the festive period because I feel as though we looked like a very solid team."
