David Moyes would be a fool to let Javier Hernandez leave in January, based on his transfer market history. 

Chicarito's future has come under the spotlight recently, following a curious decision to retweet compatriot Carlos Vela's warning, that he should leave in order to find first team football. 

The former Arsenal man tweeted: "He is one of the best finishers in England and deserves chances under the new coach.

"If he doesn't play regularly he will need to think about leaving."

It's no surprise the Mexican has found himself limited for opportunities this season, given the form that Wayne Rooney and Robin van Persie are currently demonstrating. 

However should the poacher decide to leave in January, Manchester United could suffer this season as a result. 

During Moyes' tenure at Everton, it is true that he built and maintained a successful club, which displayed consistency with limited resources. 

However during the Scot's time at Goodison Park, he managed to sign over 10 strikers in his 11 years.

The likes of Yakubu, Jo, Louis Saha, James Beattie, Andy Johnson, Nikica Jelavic and even Jermaine Beckford, just to name a few, all got their opportunity, but not a single one proved their worth. 

So it should come as no surprise then, that Moyes most prolific goalscorer whilst at Merseyside was Australian midfielder Tim Cahill. Scoring 56 goals in 226 games for the Toffees. 

This tells you one thing, Moyes struggles to find and buy a consistent goalscorer. Something that Hernandez is. 

Since the former Guadalajara hit-man joined United in 2010, he has found it hard to hold down a regular starting role. Despite this if you look at the goals he has scored, and the importance of them at the time, it's quite clear how valuable of an asset he is. 

Converting 34 goals in 81 appearances at the top level is great achievement for the 25-year old, something that Moyes has to understand. 

Given United's troubles in the transfer market in the summer, would it be wise to sell Hernandez in January? With the added risk of not signing an equal or better replacement in time?

Who would you replace him with? It's not going to be easy to convince a striker in a World Cup year, to come and sit on the bench, even if you are Watching Rooney and RVP. 

It's no secret that the Mexican needs first team football ahead of next year's World Cup. 

However should Moyes choose to sell, he will have to give something back to the fans, in order to convince them it was the right decision.
