The 23-year-old becomes the Bees’ fifth signing of the summer and he has signed a four-year deal at Griffin Park, with the club holding the option to extend this for a further year until 2024.
Jensen struggled for game time at Celta last term as he made just six appearances in La Liga, but this was partly due to his first half of the season being hampered by an injury.
Despite his struggles in Spain, the midfielder arrives in West London with high pedigree as he has played 15 times for the Danish Under-21 side, and most recently featured in the European Championships last month.
Jensen becomes the second Dane signed by Thomas Frank this summer, after Christian Norgaard joined from Fiorentina earlier this summer. Frank’s latest recruit has now joined the squad in Austria, and he will start training later in the week.
This is another impressive move from Brentford, who have played a blinder in the transfer window so far.
Frank looks like he is assembling a squad ready to compete for promotion, and Jensen will provide his fellow countryman with further depth to his midfield options.
Jensen’s appearances for Celta were limited, but when he did play he operated in numerous positions across the midfield. He clearly has a strong footballing brain which means he can be flexible in Brentford’s various playing systems.
He seems to be a good fit for Brentford, and his adaptation period at the London club will be helped by having Frank, Norgaard and Henrik Dalsgaard close by.
