Southampton have seen some of their best players transfer to Liverpool in recent years - and they'll come up against some familiar faces when they host the Reds in their Sky Live EFL Cup semi-final first-leg on Wednesday.
Sadio Mane may be away on international duty at the Africa Cup of Nations, but Adam Lallana, Dejan Lovren and Nathaniel Clyne could all feature against their former club at St Mary's.

Including Rickie Lambert - who has since left Liverpool for West Brom and been loaned out to Cardiff - Liverpool have spent over £95m on Southampton players in the past three years.
Here, Southampton legend and Sky Sports pundit Matt Le Tissier gives his assessment on whether the five transfers were a success - and how Southampton coped with the loss…
Rickie Lambert - £4m, June 2014
Le Tissier says: I'm not sure he'll regret leaving Southampton as Liverpool were his team as a boy and he'd always dreamed of playing for them, but obviously his career went downhill pretty quickly after that. However, I'm not sure he would have swapped getting the chance to pull on that famous red shirt for playing in the Premier League for a few more seasons.
Adam Lallana - £25m, July 2014Le Tissier says: Lallana was probably the one I was most disappointed to see go. He was always somebody who I loved going to watch and I think he's turned out to be an excellent signing for Liverpool. I'd imagine he's one of the first names on Gareth Southgate's England team-sheet and one of the few players who came out of the European Championships with any credit.
Dejan Lovren - £20m, July 2014
Le Tissier says: It was a dodgy first season at Liverpool for Lovren, that's for sure, and he took a while to win over the fans, but I think he's finally got there and is showing the form he did at Southampton. However, we did pretty well in terms of replacing him with Toby Alderweireld and Virgil van Dijk at the time, two of the best centre-backs in the Premier League.
Nathaniel Clyne - £12.5m, July 2015
Le Tissier says: Clyne is a very, very good full-back and we missed him a fair bit last season. Cedric Soares is starting to show he's good enough to replace him, with winning the Euros with Portugal obviously helping his confidence. When we had Clyne and Ryan Bertrand as full-backs we probably had one of the best pairings in the league.
Sadio Mane - £34m, June 2016
Le Tissier says: Mane seems to have shown more consistency at Liverpool, possibly because he's surrounded by a lot of good attacking players, which obviously helps. I'm quite pleased he's away for the Africa Cup of Nations on Wednesday night - but I'd still rate Lallana as our best export to Liverpool, with Mane a close second.
