Celtic manager Neil Lennon remains coy on which players he will try to sign during the January transfer window.
The SPL giants have been linked with Maritimo's Baba Diawara, as well as Scotland international striker Jordan Rhodes, and Lennon himself watched Huddersfield Town's League One game against Charlton Athletic at The Valley on Monday.
However, the 40-year-old is eager not to be dragged into transfer speculation and focused instead on his side's Europa League Group I clash with Atletico Madrid on Wednesday.
"I was down watching the game," said Lennon. "I'm not here to talk about any players, particularly players who are under contract with another club.
"We are not even in December yet and I'm being asked questions about players coming in or going out.
"I'm preparing a team for a big European game and I'm not prepared to talk about much else really.
"We have our eye on a couple of targets but there are no guarantees of getting deals done.
"We have come through a bit of a rough period in the season and we are on a good run now.
"Confidence is high in the squad and there is a good feeling around the club again and we are looking forward to the upcoming games.
"When January comes we will deal with it behind closed doors as best we can."
Celtic are third in their group in the European competition with five points from four matches, two behind Atletico and Udinese in first and second respectively.
