It's been a season of mixed fortuned for Barcelona this season. An early season blip in form has possibly cost them the defence of their La Liga title, though with a few weeks remaining in the campaign there's a chance they could still claim it should Real Madrid slip up.In the Champions League they pulled off what can be considered as the greatest comeback in football history when they managed to overturn a 4-0 deficit at the hands of Paris Saint-Germain to to win the second leg 6-1, only to see their efforts come to nothing with a 3-0 defeat at the hands of Juventus in the quarter-final.And with that in mind, Barca chiefs are looking into ways they can reassert their dominance next season by drawing up a five-man shortlist of transfer priorities to pursue over the summer window.It seems rare that a side with such talents as the Blaugrana should need to draw up a list so extensive, but there is a very real danger that they could end the campaign empty-handed, which would be an utterly disastrous outcome.So you would think that if they are in the market for new players, then they would be the cream of the crop, the best of the best, players who would fit in instantly and provide some serious competition for a number of their already established stars.But according to Spanish publication Mundo Deportivo, the club have drawn up a five-man shortlist, who, while not on a world class level, could certainly help re-establish them as the top dogs in the division.The first name on the list is Arsenal's Hector Bellerin. The club's interest in their former prospect has been no secret, and the full-back's dip in form has come at a curious time. Still just 22, he is still learning the game at the highest level, but judging by Barca's problems in replacing Dani Alves have made him a likely target.Atletico Madrid's Theo Hernandez is another player who has been linked recently, with several reports claiming that they've already beaten Real Madrid to his signature. Currently on loan at Alaves, the 19-year-old left-back has been in impressive form that suggests he could handle the step up.PSG's Marco Verratti is a player they got a good look at earlier in the year, though whether the French giants would sell is another question altogether. Out of all the players they're linked with, the Italian would be the closest thing to a marquee signing, but he won't come cheap.There could be room for another Barca academy graduate to make a return, with Gerard Deulofeu emerging as another target. The 23-year-old made two appearances for the club before being sold to Everton in 2015. Now on loan at Milan, he's been credited as one of the major factors in their recent revival.

And finally, another player who has been heavily linked is Liverpool's Philippe Coutinho. The Brazilian was seen spotted deep in conversation with Neymar and Luis Suarez after a recent World Cup qualifier, and his performances at Anfield, when not injured, have put him firmly in the spotlight in terms of transfer rumours.

The list may not blow anyone away, but it would be a big overhaul if they are able to bring all five players on board.
