Leinster head coach Leo Cullen refused to comment directly on reports they are set to sign lock Jason Jenkins from Munster, but says "it would make sense" for the province to be linked with the South African.
It's believed the Springbok is set to swap Thomond Park for the RDS when his one-year deal at Munster expires in the summer.
The 26-year-old has been unable to make an impact since arriving at the province, with a series of injuries limiting him to just one 18-minute appearance off the bench.
However, Jenkins' physical profile - 6ft 8in and almost 125kg - makes him an ideal fit for Leinster, who are looking to add depth and experience to their second row next season.
Cullen was coy when asked about their interest in the player.
"We don't normally comment on this speculation, but I can see how it would make sense for certain people's minds, for sure," he said.
"I know that Johann (Van Graan) talks very, very highly of him. He is a big man.
"You see in some of the big games, South Africa winning the World Cup and that Lions series, the emphasis particularly around the scrum and maul.
"We don’t bring a huge amount of guys in from outside as you would be well aware. Big Mike Ala’alatoa is our only foreign player.
"Mike is starting this weekend. He has had an unbelievable impact. Sometimes a bit of that experience from the outside is good for the group. Mike is also a very big man which is good. Him and his family have settled in well. He is a good member of the group. You can see the quality he brings.
"We will comment further if there is anything official to be announced."
Ala'alatoa is one of four changes for Cullen's side as they travel to Bath, looking to firstly secure a place in the Round of 16 in the Heineken Champions Cup, but also hoping to get themselves home advantage for the second leg.
The Samoa international starts in place of the injured Tadhg Furlong, with Cullen expecting the tighthead to be fit in time for the start of the Six Nations, while James Ryan's injury is also minor, Cullen adding that the second row could have featured this week if they had been desperate.
Bath come into the game rock bottom of the Premiership and out of contention for a place in the last 16 in Europe.
However, Cullen says that creates an element of danger, with the hosts having nothing to lose against the four-time champions.
"Definitely, yeah," Cullen adds, when asked if Leinster will be a "free shot" for Bath.
"That has been our mindset here looking at Bath over the last while.
"When we played (them) in the Aviva before Christmas we had lots of good stuff in the first half but we had a massive drop off and we were very frustrated in the playing group and coaching group after the game with how we managed the second half.
"That's the thing that sticks with us just trying to push that 80-minute performance. Bath have a lot of quality in their squad.
"We need to make sure that we are prepped and ready for the threats that they will bring, particularly when they are at home."
