One aspect that has been glaringly missing from Arsenal this season is a goalscorer - someone who can find the back of the net at a better rate than every two games.

Of course, this was something that was obvious, and then some, for pretty much everyone at the beginning of the season, even Arsene Wenger, which is why he bid for Luis Suarez.

However, when that bid failed, Wenger did not make a move for another striker, deciding to put his faith in Olivier Giroud, who, while showing improvements this season, is just not someone that you can rely on to carry you for the entire campaign.

How different would Arsenal's season have been had Wenger managed to sign Suarez? The Uruguayan, with his goals and assists, has undoubtedly been the main reason why Liverpool are within touching distance of a first league title in 24 years; had he been playing for Arsenal, the North London side would have been in that position, probably in an even stronger position.

But then, Suarez was never really an option, with Liverpool making it quite clear they would not sell their best player to a rival team. Gonzalo Higuain, though, was very much an option - indeed Arsenal looked nailed-on to sign the Argentina international, before Wenger's flirtations with Suarez and Napoli's quick thinking foiled that move.

Arsenal could be handed another opportunity to sign Higuain in the coming summer transfer window, with reports coming out of Italy suggesting all is not well between the striker and manager Rafa Benitez. Higuain has been substituted pretty much every time in the last few games, and the former Real Madrid forward's fuse went off after he was taken off in the weekend's game against Parma, which Benitez's men lost 1-0.

If the tense situation with Benitez and Higuain, who has scored 20 goals in all competitions this season, continues, then it could open up a window for Arsenal to swoop in, much like Napoli did last summer.

However, Wenger, currently will only be concerned about his team's alarming form, which has seen them crash out of the title race, with fourth place now out of their hands following that pathetic 3-0 defeat to Everton.

It also remains to be seen whether Wenger, who has hinted on more than a few occasions he will sign a new contract, will remain as Arsenal manager come the end of the season, with the Frenchman delaying the signing of a new deal to see how his team finishes come May.

An FA Cup victory might paper over the cracks for the immediate future, but there is little doubt that Arsenal need strengthening across the board. Wenger, perhaps, also needs to rethink his strategy against big teams, rather than just telling his players to go out there and express themselves - that has always been the Wenger way, but the Frenchman needs to realise this Arsenal side just aren't good enough to roll over any team with their style alone.

Another player that Wenger could use come next season is Jackson Martinez, who has again hinted at a possible move away from FC Porto.

"I've not renewed [my contract] with the club as yet," Colombian international Martinez told Portuguese newspaper A Bola. "It's something that we have been discussing during the season.

"As for my departure, after the World Cup, many things can happen but I am focused on continuing to do an excellent job for Porto and the rest will come with time."

Higuain, Martinez, Diego Costa, Edinson Cavani, Radamel Falcao, some of the names that can take Arsenal to the next level - if Wenger deems them to be better than Giroud, that is.
