With the start of the new season drawing ever closer, transfer activity is set to intensify as clubs look to do their business before the big kick-off.

Here, we take a look at the top five transfers that could all still happen this summer.

Cristiano Ronaldo | Real Madrid
Potential suitors: Manchester United, PSG, Monaco, Chelsea
Potential fee: £80-100m

A compelling case an be made for Ronaldo being the best player in the world following a scintillating four years at Real Madrid, scoring 146 goals in 135 league games.

Manchester United seems the most likely destination as CR7 could be tempted into a romantic return to Old Trafford.

Any transfer however would break the bank for any club, with his current value set at £88m by transfermarkt.

Gareth Bale | Tottenham Hotspur
Potential suitors: Real Madrid, Barcelona, Manchester United
Potential fee: £60-90m

The flying Welshman singled-handedly carried Spurs last season, and the club could yet pay for failing to secure fourth place and entry into Europe's most prestigious competition with Bale’s departure.

Real Madrid are the front-runners in this transfer saga - club chairman Florentino Perez has described Bale as born to play for the club and Los Galaticos have even left the number 11 shirt vacant for him. David Moyes is also understood to be keen on the winger.

Wayne Rooney | Manchester United
Potential suitors: Chelsea, PSG, Arsenal, Real Madrid
Potential fee: £25-45m

Whilst Rooney's value is higher than his potential fee, he only has two years left on his contract, and has expressed his desire to leave Manchester this summer, meaning United may be keen to offload their want-away striker.

Meanwhile, Arsenal chief executive Ivan Gazidis has insisted that Arsenal could afford Rooney's wages and fee. Chelsea though are the favourites as it stands after having an initial bid turned down, and are expected to come back with a fresh and improved bid soon. 

Cesc Fabregas | Barcelona
Potential suitors: Manchester United, Arsenal, Juventus, Manchester City
Potential fee: £35-60m

Barcelona's versatile midfielder reportedly has a clause in his contract which states that Arsenal are set to receive 50% of any transfer fee which takes Fabregas away from Catalonia, meaning that Barcelona would want an inflated price for former Arsenal player.

At this moment in time Manchester United  appear to be the only club seriously vying for his signature, making two bids, both if which have been rejected.

Luis Suarez | Liverpool
Potential suitors: Arsenal, Real Madrid, Bayern Munich
Potential fee: £30-50m

Liverpool's troubled hit-man has expressed his desire to leave Anfield this summer, citing his treatment by the press and Liverpool's lack of participation in the Champions League as the main reasons behind his request.

Arsenal have already had two bids turned down, although Liverpool are reportedly obliged to consider and discuss with the Uruguayan any bid in excess of £40m as dictated by a clause in Suarez's contract.
