Radamel Falcao is considering potential options away from Manchester United, with rumours emerging that there are concerns from those at Old Trafford about the players long-term fitness, per fichajes.net (h/t Jack Watson of Squawka).The Colombian forward has only found the back of the net on two occasions since he signed for the Red Devils on loan from Monaco in the summer. Admittedly, the players game time has been somewhat limited because of injuries, but as noted here by writer Luke Moore, Falcaos looked like a class act whenever hes donned the red jersey:The truth is that it was always going to take Falcao a while to rediscover his best form. The Colombian tore his cruciate ligaments at the start of the year and it takes players a long time to recover from those kinds of serious injury layoffs; truth be told, some players are never quite the same again.In the aftermath of the Red Devils 1-1 draw with Aston Villaa match in which Falcao scored a fine equaliserUnited boss Louis van Gaal insisted that its also up to the players teammates to help him rediscover his goalscoring touch, per Matthew Scott of Goal.com:Falcao is also dependable on his team-mates. He can be in great form, but the team has to be in great form. That allows Falcao to show his qualities.When the cross is not coming from Ashley Young, then he cannot show what he has done in the last match [at Villa].As noted by David Anderson of The Mirror, the former Atletico Madrid man has insisted he is willing to stick around at Old Trafford, and the club have an option make the deal for the forward permanent for a fee of 43.2 million. But Scott of Republik of Mancunia is clearly not getting his hopes up:At his very best, Falcao is a player worth that kind of money, for there are few better out-and-out poachers in world football. With that in mind, you suspect the prospect of a deal being made permanent will ultimately rest on whether the Colombian can stay in the team and score goals in the second half of the campaign.Rumours have also emerged suggesting that United's No. 9 could be joined by Gareth Bale in the January window. According to fichajes.net (h/t Jamie Sanderson of Metro), the Welshman is keen on a move back to the Premier League in a transfer that would amount to a world record 120 million fee.Here's a look at what Bale could potentially add to this United side:But many will argue that kind of money could be better utilised in other areas of the squad, like in midfield and defence. Romas midfield anchor Kevin Strootman is a player that has long been linked with a move to Old Trafford, and Bleacher Reports Sam Tighe assesses the chances of a January deal:Another player who could potentially be on the clubs radar is Yohan Cabaye, after it was reported by tuttomercato.web (h/t Ashley Birch of Squawka) that Tottenham are willing to bring the 29-year-old back to the Premier League. Birch mentions in his piece that United, Arsenal and Liverpool are also monitoring the situation.Cabaye has struggled to make an impression for Paris-Saint Germain this season and, given the class he showcased in the Premier League, is a sensible target for English clubs. Former player Stan Collymore has long been an advocate of Cabaye potentially moving to Old Trafford:But at this juncture, hes not the kind of player Van Gaal needs. The former Newcastle United man is a classy midfielder that shone in an advanced role in the Premier League; United need a player in the Strootman mould to add legs and defensive steel to what is an offensively loaded set of midfield options.The club could also invest that money into the clubs academy talent, and somewhat worryingly for a team that prides itself on this side of the game, up to six of the Red Devils finest youngsters are free to sign a pre-contract with a different club in January, with their contracts due to expire at the end of the current season, per James Dickenson of the Express.Stars like James Wilson, Paddy McNair and Tyler Blackettyoungsters who have all featured regularly under the tutelage of Van Gaalhave looked very promising in their recent displays in the first team, and its vital the Red Devils continue to mould young players as well as splashing the cash on mega-stars like Falcao and potentially Bale.
