Chelsea's long-term problems with their strikers have been well-documented, and their search for a proven goalscorer looks set to continue into the summer. The Blues have recently given up on signing Manchester United's Wayne Rooney as the England star is close to signing a new £300K a week deal at Old Trafford, according to The Mirror. However, Jose Mourinho could end up calling David Moyes about another one of his players. Javier Hernandez has made 141 appearances for Manchester United since signing for them in 2010 and has scored 58 goals, giving him a ratio of one goal every 2.4 games. When you factor in his 14 assists, it becomes clear that he is a better option up front than any of Chelsea's current trio. Fernando Torres has turned out 158 times for the Blues, scoring once every 3.4 games, while Demba Ba's limited appearances have seen him produce a goal every 4.4 games. Samuel Eto'o fares best of the current crop, with his hattrick against Manchester United pushing him to a goal every 2.75 games, however, the 32-year-old does not present a long-term solution for Chelsea. Hernandez has found his appearances limited at United, providing back-up for the first choice pairing of Robin Van Persie and Rooney. Even Danny Welbeck is ahead of him in the Old Trafford pecking order. The 25-year-old is desperate for regular first-team football, and according to the Daily Mail there are up to 10 clubs across the continent who are interested in securing his signature. Hernandez' agent has told Sky Sports that he will assess the situation after this summer's World Cup, where the striker will feature for Mexico. Whether his value increases after the tournament remains to be seen, however, Chelsea certainly have the financial clout to fend off any competition. They have made a £4 million profit so far this January, and the sale of Juan Mata to United should act as a sweetener if they decide to pursue Hernandez. He is currently valued at around £14 million by transfermarkt.co.uk, less than half of the £32 million that Diego Costa would cost and way below the £50+ million that would be needed to prise Edinson Cavani or Radamel Falcao away from Paris Saint-Germain and Monaco respectively. A move for Hernandez would pave the way for Ba to leave Chelsea, with Torres also likely to head for pastures new. Romelu Lukaku's return from his loan spell at Everton in the summer would allow a formidable partnership to be formed between the big Belgian and the little pea as Mourinho sets his sights on silverware next season.
