Luke Shaw took great pleasure in seeing Romelu Lukaku's Inter Milan crash out of the Champions League on Tuesday night.
Inter lost 2-1 at home to Barcelona and their exit from Europe's premier competition means they will now enter the knockout stages of the Europa League.
There is a subsequent chance that Inter could be drawn against Manchester United when the draw for the next round is made on Monday in Nyon.
And that gave Shaw plenty of reason to mock former United team-mate Lukaku just a couple of hours after Inter's defeat at the San Siro.
He tweeted an old post of Lukaku's, which showed a picture of the striker smiling followed by the smiley emoji and a caption that read: 'UCL'.
Shaw couldn't resist and added: 'Welcome back'.
You sense that Shaw had been waiting to get his own back for some time after Lukaku tweeted the sprinting stats for the whole of the United team at the start of the season.
