Yes keep dreaming whilst you day sleeping
Messi plays the same standard he did all his life in the La Liga & yet the trophies have dropped post Iniesta & Xavi. Ronaldo scores the same amount in the La liga as Messi always has done because its a very poor league which acres and acres of space for attacking players. Ronaldo if he stuck about at Real Madrid like Messi sticks around at Barcelona - Ronaldo would still be doing what he always done because its just way too easy..
Only time Messi had to adapt to a team that he didn't grew up from the age of 13 and with growth hormone injections - he failed with Argentina except for Olympic medals. So I highly doubt why Messi would be doing wonders for Juventus (especially when he can't play with his partner Higuaín in a national team anyway), never mind teams like Bournemouth or Udinese
Would he still be good? For sure. But absolutely no way would he have the ease of playing for Barcelona and playing with the legendary Barcelona players and those la liga teams where he gets 59+ goals per season.
It's a bit like saying that Giggs and Scholes were cowards for not transfering to Juventus or Inter to prove they could cut in Seria A. They were academy products, fans of their own club and played for the biggest club in britain and in the top 3-5 in the world. They had no real reason to want to out. Same with Messi. He's been with Barcalona since he was 14 and Barca and Real Madrid are the dream clubs for latin players. What possible club could Messi transfer to that would be a step up? He destroyed fergies united in 2 CL finals. He destroyed Bayern. Him and Barcalona have reguarly destroyed Real madrid in the CL and classsico's. He has more goals against the top PL clubs than the best PL strikers have.
He's the all time top scorer for Argentina, despite often playing as a Nr 10 who drops deep to dictate the build up play. 4 international silver medals is better than no medals at all. If Higuain hadn't botched his one vs one in the WC final, then Messi would be a world cup winner as well. Its all about fine margins isnt it? If a nothing player like Eder hadn't scored a worldie against France in the final, they most likely would have won feck all. With regards to Messi's growth hormone treatments, you seem to know feck all about hormone replacement therapy. His treatments that he has the same lvls of growth hormones that healthy people have. No more and no less. It's not doping.
Ronaldo Major Finals
2008 cl final: Good performance scored our only goal. fecked up his penalty in the shootout and what would have been scapegoated for losing the shootout if Terry hadn't slipped
2009: CL final. Barely saw the ball. Took ridicoulous potshots from a distance. Meanwhile the midget messi scored a lobbed header against Vidic, Ferdinand and VDS.
2014 CL Final: Mainly invisible. Bale bailed them out and Ronaldo scored a penalty in the 120 minute to take it to 1-4 and proceeded to celebrate like he won the final one his own.
2016 CL final: Invisible mainly. Scored the last goal in the pentaly shootout.
2017 CL Final: His best CL final performance. Scored a fine brace against juventus.
2018 CL final: Completely invisible. Karius gifted them 2 goals and Bale scored a worldie that is probably the best CL final of all time.
Euro Final: Went off injured early in the game. Then basicly tried to outdo to the coach on the touchline to make it all about him. Eder scored a worldie that bailed them out.
