Who should top European clubs buy if they had a huge transfer budget?

With just over a month of the ongoing season remaining, the transfer rumour merry-go-round has already started. Real Madrid have made the first big move ahead of the summer transfer window by agreeing terms with FC Portos right back Danilo. It is safe to assume that a battle to get the signature of some of Europes most coveted players will break out between some of Europes biggest clubs.So here is a list of players some of the top clubs from around Europe should go for if they have the transfer budget to do the same.Note: We have omitted FC Barcelona from the list because of the transfer ban they will be serving in the summer. We have also excluded FC Bayern Munich as they already have a well-balanced squad and are unlikely to splash the cash heavily this summer.Market Price of players have been obtained from TransferMarkt.

#1 Manchester United

Mats Hummels

Market Price: £26m; Estimated Transfer Fee: £35m

Manchester United will need experienced centre backs of better quality when they return to the Champions League next season and Hummels could be available after the eventual departure of Jurgen Klopp from Borussia Dortmund. If the German arrives on England's shores, it could also signal the end of Jonny Evans’ spell at United as the Scot has now fallen below Chris Smalling, Marcos Rojo and Phil Jones in the pecking order.

Memphis Depay

Market Price: £11m; Estimated Transfer Fee: £15m

Depay has been linked with a move to the club ever since Louis van Gaal took over and the youngster will be keen to move to a more challenging league to push his career forward. The Dutchman prefers playing down the left flank and will have to challenge Ashley Young for a starting spot which could help bring the best out of both players and help in competing on different fronts.

Gareth Bale

Market Price: £58m; Estimated Transfer Fee: £80m

Gareth Bale’s Real Madrid career is coming under fire following some erratic performances and Manchester United is one of the very few clubs that can afford the Welshman’s transfer fee. United may be tempted to play him down the left wing which brought out the best in him while he was at Spurs. But they already have options there in Young and possibly Depay as well, while on the right United are currently playing Juan Mata, who is not a natural winger and Bale would be a better fit than the Spaniard.

Nathaniel Clyne

Market Price: £9m; Estimated Transfer Fee: £15m

Van Gaal has put his faith in Antonio Valencia as a right back this season, but that is surely not a decision for the long run. The Dutchman will be keen to bring in a right back and Clyne, who is enjoying a great season, is an obvious choice. If the Englishman arrives at Old Trafford, then out of favour full back Rafael could be on his way out.

Total Expenditure: £145m
