Arsenal boss Mikel Arteta insists he has no regrets over his squad clearout performed this season.

Injuries to Kieran Tierney and Thomas Partey, plus the goals drying up again, have opened Arteta up to scrutiny after he let a string of players leave in January without any new additions.

Five senior players were among the departures — Pierre-Emerick Aubameyang, Ainsley Maitland-Niles, Pablo Mari, Calum Chambers and Sead Kolasinac — plus emerging striker Folarin Balogun. But Arteta insists he has no regrets.

"They were players that we did not really use," he said. "And you put them in the context now, I don't know how much they would have played.

"You don't know, I don't know. We made a decision on what we believed was the right thing to do for the club, then for the players who were asking for the opportunity to play football because they didn't have any minutes in several months."

However, Arteta admits things could change the this summer.

Arteta said: "Both competitions (the Champions League and Europa League) require a much larger squad because the number of games you play is much bigger, so I don't think it makes a lot of difference (which competition they qualify for).

"If you can afford it and we don't have to do the turnaround in the squad that we've had to do, if you ask me what I want it's 22 outfield players and three goalkeepers."
