The former Barcelona left-back spent the first half of the 2024/25 season on loan at Parkhead from the Catalans before cutting short his stay in Glasgow to join Cesc Fàbregas' ambitious Serie A side.

That decision has worked out spectacularly for the 22-year-old. Valle is now an established member of a Como team making waves in the Champions League, while his performances have also earned him a regular place in the Spain Under-21 set-up.

But Valle believes his brief spell at Celtic played an important role in his development, despite fans in Glasgow not seeing him reach the level he has now soared to.

Speaking to MARCA, the defender reflected on the very different demands he encountered in Scottish football and revealed that Rodgers' tactical approach left a lasting impression on him.

"I worked hard because it's a different league. Very tough, very physical," Valle said. "Even though the technical level isn't high, it's hard to win.

"Brendan Rodgers' style of play caught my attention. I ended up learning some midfield concepts."

Valle had arrived at Celtic after spending pre-season with Hansi Flick at Barcelona. He revealed he enjoyed working under the German and felt comfortable when deployed at right-back, but his preferred position remained on the left.

With Alejandro Balde and Gerard Martín providing competition there, Valle was presented with the chance to move to Celtic and play Champions League football.

He decided to take it.

Valle said he held a "very friendly and honest" conversation with Flick before discussing his options with his family, girlfriend and representatives. Once the Celtic opportunity emerged, he was determined to embrace the challenge.

He went on to make 19 appearances for the Hoops before his Celtic loan was ended midway through the campaign and he switched to Como.

It proved the beginning of another major chapter in his development.

Fàbregas has established Como as one of European football's most exciting emerging sides and Valle has become an important figure in the Spaniard's team. His loan move was eventually turned into a permanent transfer, with Como paying around €6million to Barcelona.

Valle has since found himself back on the Champions League stage. He played the full 90 minutes and provided an assist as Como demolished Lens 9-1 earlier this month, underlining the remarkable progress he and his new club have made.

And while Rodgers caught Valle's imagination in Glasgow, Fàbregas is now having a similarly profound influence.

The former Celtic defender described the Como boss as hugely ambitious, possessing a winning mentality and fearing "nothing and no one".

Valle's development has continued at pace in Italy, with the former Barcelona youngster now flourishing under Fàbregas after his short but educational spell under Rodgers in Glasgow.
