In terms of posession and defensive style yes, but Maguire and Varane are by a mile our two best aerial defenders, and set pieces absolutely will be a struggle for us with a pairing of Lindelof and Martinez. We already struggle defending them as it is. Maguire in good form is a better option for our overall team than Lindelof in good form. Whether he can get back there is up for debate, but people are comparing his form in a disastrous squad last year and the early days of this season (where Martinez looked equally poor) are not really being fair in their assessment. If he comes in and has a run of games while still making the same errors, then fair enough, but he deserves a chance to redeem himself when he has obviously shown to have quality at other times of his United and England career.
