Monaco added to the capture of Bulgaria striker Dimitar Berbatov by signing powerful Tunisia defender Aymen Abennour right at the end of the January transfer window.

Tunisian international Abdennour, 24, signed from Monaco's Ligue 1 rivals Toulouse, initially on loan but with an option to turn the deal into a permanent four-year agreement in the summer.

"Aymen Abdennour is a very solid defender with a profile that we didn't have in the squad. We have been following him for a long time and so we are very satisfied to have reached a deal with Toulouse to bring him to Monaco," vice-president Vadim Vasilyev told the club's website.

That deal was passed just before the January transfer window slammed shut and came after the announcement that former Bayer Leverkusen, Tottenham Hotspur and Manchester United striker Berbatov had joined until the end of the season from Fulham to cover for the injured Falcao.

Falcao suffered a serious knee injury playing in a French Cup tie last month and is set to miss the rest of the season as well as the World Cup in Brazil.

After making major waves in the transfer market last summer, Monaco were one of the busiest French clubs again in the January window, although in general Ligue 1 is spared from the chaotic scenes that come on the final day of the window in England.

Monaco had earlier signed Nigerian left-back Elderson Echiejile from Braga in Portugal and giant Ivorian striker Lacina Traore from Anzhi Makhachkala, although the latter was then loaned out to Everton.

Paris Saint-Germain settled for just the one January signing in France midfielder Yohan Cabaye, who joined from Newcastle United for a fee of up to 23 million euros (£19m, $31.4m) including bonuses on Wednesday.

Cabaye made his PSG debut from the bench in Friday's 2-0 Ligue 1 win against Bordeaux and almost marked the occasion with a goal, hitting the post from a late header.

The most notable moves elsewhere in France on deadline day came at Saint-Etienne, where Algeria left-back Faouzi Ghoulam was sold to Napoli for a reported six million euros ($8.1m) and was replaced with Benoit Tremoulinas, capped by France but who had been with Dynamo Kiev.

Les Verts also brought back France midfielder Josuha Guilavogui on loan, six months after selling him to Atletico Madrid.
