Manchester United have had a rich history with French signings. From the days of Eric Cantona to those of Paul Pogba and Anthony Martial of late - the country has given the English club so many talented stars.Time and again managers such as Sir Alex Ferguson, Louis van Gaal and Jose Mourinho have looked at signing French-born players to solve their problems and why not? The country boasts of winning two FIFA World Cups, two UEFA European Championships and two FIFA Confederations Cups. And those tournaments have brought to the fore some of the brightest stars, making the choice easier for Manchester United managers when it comes to new signings.Manchester United's great and not-so-great French signingsBut not all those signings have found success at Old Trafford. The likes of Laurent Blanc, despite being regarded as one of the greatest French players, was not one of Sir Alex Ferguson's more successful signings.It also came as a surprise to many when the legendary manager made William Prunier one of his loan signings from Bordeaux back in 1995.However, the general pattern has been a positive one. Undoubtedly, one of the greatest French players, Eric Cantona, gave the number 7 shirt a new meaning following his arrival from Leeds United in 1992.Eric Cantona.That's it.

Despite his spell not lasting for more than four years, he remains one of the biggest French signings for Manchester United.Manchester United are now ushering in a new era with the signing of Raphael Varane from Real Madrid. Though the defender is yet to be unveiled, the excitement among fans is noteworthy. Along with Jadon Sancho, Varane is one of the most high-profile signings of the Ole Gunnar Solskjaer era and the latest Frenchman expected to ply his trade at Old Trafford.Ahead of Varane's baptism in Manchester, we profile five of his fellow countrymen to have had the greatest impact at Manchester United in the past.#5 Mikael SilvestreManchester United Training & Press ConferenceMikael Silvestre decided to make the switch from Italy to England back in 1999 for a fee in the region of £4m. The Frenchman had an offer from Liverpool as well but decided to opt for the Red Devils.He was the most high-profile of the five signings Manchester United had made that summer. Ferguson had a preference for players who could perform multiple roles on the pitch and Silvestre fitted the bill.The defender was used both as a centre-back as well as a full-back by his manager. As a full-back Silvestre had the chance to show his attacking skills.Following the departure of Jaap Stam in 2001 Silvestre became the leader of the pack and stayed that way until the signings of Nemanja Vidic and Patrice Evra in January 2006.Meanwhile, Silvestre's issues with injuries had dented his sharpness and he no longer found himself at the top of Sir Alex Ferguson's pecking order, eventually deciding to bid adieu to Old Trafford in 2008.Arsene Wenger still had faith in the Frenchman's abilities and made him one of his utility signings. Silvestre notched up 361 appearances in all competitions for Manchester United and also had stints in the MLS and Indian Super League after leaving Arsenal.#4 Louis SahaManchester United '99 Legends v FC Bayern LegendsLouis Saha was on a goal scoring spree for Fulham when Sir Alex Ferguson spotted him. The season before joining Manchester United, the Frenchman had scored a resounding 22 goals in 35 appearances in a Fulham shirt.Manchester United at the time had become over-relient on just one striker - Ruud van Nistelrooy. Ferguson felt the need to find someone who could give him goals day-in, day-out.Diego Forlan's move from Independiente had failed miserably as the young Uruguayan failed to suit himself to the demanding nature of the Premier League.From that aspect, Saha suited well having already proven himself as a goal getter in the division. Ferguson, though, preferred to use Saha as a back-up and most of his appearances during the first season came off the bench.Manchester United fans only started to see sparks of Saha's brilliance in his second season as he found himself involved in as many as 22 goals in 30 appearances.🗣 Louis Saha on Man United post-Fergie"You might copy it, but it will never be the same"One of a kind.#MUFC pic.twitter.com/vClhbLrc81— Ladbrokes (@Ladbrokes) June 3, 2019Following the departure of Van Nistelrooy, Saha started to take centre-stage but that was when his issues with injury began to crop up. The following season was his worst as he could manage only 17 league appearances and Ferguson was forced to let him go.Saha joined Everton in 2008 and proved his mettel there as well, scoring as many as 34 goals over the next four seasons.The pressure of performing at the highest level at a club like Manchester United might have taken a toll on his slender figure but Saha remains one of the best French signings for Manchester United.
