Manchester United defender Raphael Varane has claimed that he welcomes competition for places ahead of the imminent arrival of Lisandro Martinez.The Red Devils announced this week that they had reached an agreement to sign the 24-year-old centre-back from Ajax. Martinez played under new United boss Erik ten Hag for three seasons in the Eredivisie.BBC Sport@BBCSportIt was tough for everyone at Old Trafford last season, but Raphael Varane is sure he made the right choice in joining Manchester United.#BBCFootball20617It was tough for everyone at Old Trafford last season, but Raphael Varane is sure he made the right choice in joining Manchester United.#BBCFootballThe Dutch boss switched club captain Harry Maguire to the right-side of central defense for the pre-season friendly against Crystal Palace in preparation for the arrival of the left-footed Martinez. This would appear to put Varane's place in jeopardy despite the player moving from Real Madrid last summer on a four-year deal.The 29-year-old insisted though that competition for places is what United need, as he told BBC Sport:"Competition is good for the team. Harry is a very important player for us. He's the captain and obviously, he has a lot of good qualities. The team will always be better with this competition. Every great club is like this. If everyone wants to fight for the team, that's a good thing."United Zone@ManUnitedZone_Varane: “Competition is good for the team. Harry [Maguire] is a very important player for us.

He's the captain and obviously he has a lot of good qualities.” #MUFCRaphael Varane insists he doesn't regret leaving Real Madrid for Manchester UnitedThe France international left the Bernabeu last summer following ten successful seasons in which he won the Champions League four times.He moved to Manchester United last summer and endured numerous injury problems, which restricted him to just 29 appearances across the campaign. The Red Devils finished sixth at the end of a disastrous season.Meanwhile, Madrid captured their 14th Champions League following an incredible journey to the final. When the World Cup winner was asked if he regretted making the switch to the Premier League, he replied:"No, absolutely not."Varane added:"In football, you have to challenge yourself and try to improve. I wanted to live another experience after 10 years in the same place. The Premier League is absolutely fantastic and Manchester United are a great club. There was no doubt about my decision."The centre-back was also asked about his side's chances of catching rivals Manchester City and Liverpool anytime soon. He replied:"It's a new season. A new start. Confidence is important and we lost confidence when we lost some games. But I think we have great potential. The new manager is very positive.""He wants this energy and to press high up the pitch, with more space behind our backs. That is maybe more offensive but it is football we really enjoy, so that is a good start."United Zone@ManUnitedZone_While Arsenal primarily saw Martinez as a left-back who could compete with Kieran Tierney for a place, United view him as a centre-back of a different profile to rival Harry Maguire, Victor Lindelof and Raphael Varane [@TheAthleticUK]5749264While Arsenal primarily saw Martinez as a left-back who could compete with Kieran Tierney for a place, United view him as a centre-back of a different profile to rival Harry Maguire, Victor Lindelof and Raphael Varane [@TheAthleticUK] https://t.co/ekRXzfI4zM
