Arsenal boss Arsene Wenger believes introducing a quota-based system to the Premier League would be counter-productive.
Rangers boss Stuart McCall says he feels sorry for Gael Bigirimana, but admits he should never have been signed.
The Brazilian full-back has spent the last six years at La Liga giants Barcelona, helping them to 16 major titles.
He is, however, facing an uncertain future, with his current contract set to expire in 2015.
It has been reported that Barcelona may be willing to cash in on his services this summer, rather than risk losing him for nothing in 12 months' time.
The likes of Paris St Germain, Chelsea and Manchester City have been heavily linked with the 30-year-old, with a £15million deal mooted, but Alves maintains that he is not looking past the end of the season as Barcelona once again find themselves challenging for domestic and European honours.
He said in Le 10 Sport: "We've been talking about my future at the club since the year I arrived.
"I live in the moment, I take every year as it comes.
"For me, it's a compliment that some big teams are interested in me, that means I'm doing my job. But the truth is that I am here, I see my job as very intense every year.
"I think for a story to work, both parties must agree, a bit like in a relationship. Otherwise, it separates. At present, I know that both parties are satisfied."
