The transfer window has opened and big teams like Real Madrid and have already made their mark on it, making multiple signings and strengthening their bench or adding to the first team.
However, there are other clubs who have some major holes in their squad, and are being linked to players who can potentially strengthen their squad, but have not completed any transfer yet.
Here are four such big teams.
4. Tottenham Hotspur
The Champions League finalists have finally completed the embargo placed on them due to the financial demands of the construction of the new stadium and reportedly have a huge budget to spend on transfers.
Manager Mauricio Pochettino will mostly be happy with the first team he has, but needs a player or two to add quality in the midfield department, and Giovani Lo Celso and Tanguy Ndombele have been linked to them.
To add depth however, Spurs also look like they need a striker, as an injury to Harry Kane leaves them with an aging and immobile Fernando Llorente.
Arsenal's issues are completely opposite to that of their North London rivals, as the Gunners have reportedly spent a lot in past transfer windows and lack a proper budget, with €50 million being reported as the money Emery has to plug the holes his team has.
Emery's side have conceded a dangerous amount of goals in 2018/19, owing mostly to a high back line and injury issues to key components of the defence.
With star midfielders Aaron Ramsey departing and Lucas Torreira potentially set for a move to Italy, he also has a very poor midfield core to work with next season and risks going through a disastrous season if not for a miracle signing who can help the team majorly.
Barcelona are the favourites to sign Atletico Madrid talisman Antoine Griezmann for a mammoth €120 million, with the move set to be announced in the early days of July. However, the Catalans have a tendency to struggle with negotiations and finalisation, as it once happened with the Frenchman before, so the fans will rest well only when it is announced.
Similarly, reports have emerged that they are in the chase to bring Neymar back to the club, but that could result in Griezmann's deal being scrapped due to financial restrictions. This has thrown fans a bit off kilter, but it will be a long, long window as they hope to see either of the two signed or best case scenario, both of them finalised.
1. Manchester United
Manchester United's transfer issues are well publicised, with the board in chase for every player who has a transfer tug-of-war behind him. The latest player they became a victim of for this was Alexis Sanchez, who has practically wasted 18 months of his career at Old Trafford by sitting on the bench or playing poorly.
Reports this summer have been encouraging, with the Red Devils linked to players like Aaron Wan-Bissaka and Sean Longstaff, but it seems like old habits die hard, as United were reportedly in the chase for coveted prospect Matthijs de Ligt, only recently pulling out due to his wage demands.
Ole Gunnar Solskjaer needs a major overhaul without a speck of doubt, but United have not made any major signing as yet.
