Jose Mourinho has launched a fresh assault on Arsène Wenger and Jürgen Klopp over their criticism of Manchester United’s move for Paul Pogba by claiming the Arsenal and Liverpool managers cannot contemplate breaking the world transfer record because they are not at big enough clubs.

United finally completed the £89 million signing of Pogba on Tuesday – four years after losing the France midfielder to Juventus for just £800,000 in compensation – as they beat Real Madrid to his signature.

The deal, which eclipses the previous world record fee of £85.3 million that Real paid Spurs for Wales forward Gareth Bale in 2013, was described as a “watershed moment” for the Premier League by Gary Lineker.
