3. Accommodating both Romelu Lukaku and Marcus Rashford in the starting line-up
Both Lukaku and Rashford have performed reasonably well in the last few matches and scored some goals too. Lukaku now has 9 goals from 25 matches this season, whereas Rashford has 7 from 25. However, it would be a challenge for Solskjaer to accommodate both of them in the starting line-up.
In order to do so, Solskjaer might have to drop Jesse Lingard from his starting line-up and start Rashford on the right flank. Anthony Martial on the left and Lukaku as the centre-forward.
Lukaku’s battle against Tottenham centre-back Toby Alderweireld should be an absorbing one as both of them are big and physically strong. Both Martial and Rashford are quite capable of cutting in from the flanks and entering into the opposition penalty box. Therefore, United’s proposed front 3 should pose some serious troubles to the Tottenham's defenders.
