Inter Milan and PSV have been battling it out on social media in attempts to win the support of Brazilian legend Ronaldo ahead of their Champions League clash.
The legendary striker is likely to have a keen eye on Wednesday's Group B match up, having represented both clubs during his illustrious career.
Inter and PSV were both keen to gain Ronaldo's support this week and got locked into a light-hearted back-and-forth Twitter squabble.

The Italian side were the creators of the row by asking Ronaldo which team he will be supporting. PSV immediately riposted, writing: 'Obviously us'.
Inter then fired back by posting a video of the Brazilian's best goals for the club and writing: 'Are you sure? I mean, he did score some of his best goals for us!'
The Dutch side weren't convinced and gave Inter a taste of their own medicine by sharing a video of his best strikes in a red and white shirt.
Inter were quick to remind everyone that he was crowned the Ballon d'Or and FIFA World Player of the Year winner during his time with them.
But before PSV could respond, like splitting up two quarreling siblings, Ronaldo stepped in and wrote: 'Come on! I have wonderful memories with both teams. Good luck!'
PSV was where Ronaldo started his European venture after a glut of goals in his first full season as a senior player at Cruzeiro earned him a move to the Dutch club in 1994.
The striker banged in 54 goals in 57 games for the club during his two-year stint in Holland before moving to Barcelona and then Inter.
He continued to find the back of the net with regularity in Italy and netted 59 times in 99 games and also won the UEFA Cup with the club.
Ronaldo's performances for them saw him named among the four inaugural inductees into the Inter Milan hall of fame earlier this year.
He retired from football in 2011 and is now the majority owner of La Liga club Real Valladolid after buying a 51 per cent controlling stake in the club for £27million last month.
