Won nothing with Ajax?

Van Gaal was Ajax manager from 1991 until 1997 and had a very successful tenure. Under Van Gaal, Ajax became the Eredivisie champions three times, in 1994, 1995 (notably going the entire 1994–95 season unbeaten in both the league and the Champions League) and 1996. He also led Ajax to the KNVB Cup in 1993 and the Johan Cruijff Shield in 1993, 1994, and 1995. On the European scene, Ajax captured the UEFA Cup in 1992 and the UEFA Champions League in 1995 after beating Milan in the final. The latter win was followed by a 5–1 aggregate win over Real Zaragoza in the 1995 UEFA Super Cup. Late in 1995, Ajax beat Brazilian side Grêmio on penalties to win the Toyota Cup (formerly Intercontinental Cup). Ajax were also Champions League runners-up in 1996 after losing to Juventus on penalties.
Ajax was so successful under Van Gaal's leadership that during the 1990s, the Dutch national team was dominated by Ajax players such as Patrick Kluivert, Marc Overmars, Dennis Bergkamp, Frank and Ronald de Boer, Edgar Davids, Clarence Seedorf, Winston Bogarde, Michael Reiziger, and Edwin van der Sar.
